Love Letters in History: Who Wrote Them, Where They Are Held and What the Conventions of Each Period Were

The question is not whether people loved in the past, but how they were permitted to say so. The surviving letters answer it with a precision no memoir can match. Historical love letters show that emotional expression was governed by epistolary convention, postal economics, literacy rates and the legal status of the writer. Those constraints shaped what could be committed to ink and paper. This guide names six real letters, their writers, their recipients, the archives that hold them and the conventions that dictated their form. If you are researching a courtship or writing a wedding speech that quotes a source, the artefacts below are where the evidence lives. Skip the romantic generalities. The material facts of paper, ink and censorship are the story.

The Tablet And Its Ritual Purpose

The oldest known love text is not a letter but a sung poem, written on a clay tablet in Sumerian cuneiform around 2000 BCE. The tablet, often called The Love Song of Shu-Sin, was excavated at Nippur in what is now Iraq and is held in the Istanbul Archaeology Museums. It records a courtship ritual: the king Shu-Sin, a mortal stand-in for the god Dumuzi, is addressed by a priestess who speaks the lines of the goddess Inanna. The language is Sumerian. The surviving transcription, made by scholar Samuel Noah Kramer in the 1950s, preserves lines about the beloved being sweet as honey and lovely as a date. The convention here is not private correspondence but public liturgy. The text was performed, likely at a sacred marriage ceremony, and its purpose was to ensure agricultural fertility. There is no sender, no recipient in the personal sense, and no expectation of a reply.

What Clay Reveals About Love

What the tablet reveals is that erotic love was a legitimate subject for monumental culture thousands of years before the private letter existed. The medium of clay meant the text was durable but heavy, and the act of writing was the province of trained scribes, not lovers. Literacy rates in Sumer are estimated at under five percent. This is not a love letter in the private sense; it is a state-sponsored religious text with love as its subject.

Seeing The Tablet

If you want to see it, the tablet is on display in the museum's Mesopotamia gallery. The published transcription appears in Kramer's The Sumerians: Their History, Culture, and Character, which remains the standard scholarly edition. Check the museum's current display list before going. Tablets rotate in and out of storage, and the one you have read about may not be on the wall on the day you arrive.

The Manuscript And Its Rules

Jump forward three thousand years to the most famous medieval exchange in European history: the letters between Peter Abelard, the philosopher, and Héloïse, his former student and secret wife, written in Latin between 1132 and 1135. The letters survive in several manuscript copies from the 13th and 14th centuries. The earliest complete manuscript is held at the Bibliothèque nationale de France in Paris, shelf mark BnF MS lat. 2923. Héloïse writes to Abelard after he has been castrated by her uncle's men and she has entered a convent. The exchange is a theological and personal argument about love, duty and the nature of God. The convention is courtly love, which in the 12th century meant secret correspondence, the use of intermediaries to carry letters, and coded language that could survive interception. Andreas Capellanus's De Amore, written around 1185, codified these rules: letters should be brief, should open with a formal salutation, and should avoid naming the beloved directly in case the messenger read them. Abelard and Héloïse follow this script even while subverting it. Héloïse's first letter refuses the formal servant-to-master address and instead writes as to her lord, or rather her father, to her husband, or rather her brother.

Material Facts And Provenance

The manuscripts themselves are parchment, written in a clear book hand. The language is medieval Latin, not the French of daily speech. These letters were copied and circulated as literary works within decades of their composition, which means the surviving text is not the original but a polished transcription. The provenance runs through the Paraclete, the abbey Héloïse led, and the copies made there for other religious communities.

How To Read Them

The published scholarly edition is the Latin text with facing translation by Betty Radice, published by Penguin under the title The Letters of Abelard and Héloïse. It includes the full correspondence and Radice's introduction situating the letters in their ecclesiastical context. The physical manuscript is not on open display. Request it in the BnF's manuscripts reading room, which requires a reader's card issued on production of identification and proof of research need.

Surviving Letters And Their Hand

The letters Napoleon Bonaparte wrote to Joséphine de Beauharnais between 1796 and 1814 are the most famous wartime correspondence in French history. The majority are held at the Bibliothèque nationale de France, with others in private collections and the Musée de la Lettre et du Manuscrit in Paris. They are written in French, in Napoleon's rapid, uneven hand, on whatever paper was to hand. Early letters are on thin campaign paper, later ones on heavier letterhead. The convention is the courtship letter of the revolutionary period, which had shed the formal salutations of the ancien régime. Napoleon addresses Joséphine as mon amie or ma petite Joséphine and signs Bonaparte without title. The language is florid by modern standards but direct for its time. I wake full of you, he writes in one letter in December 1795, your image and the intoxicating pleasures of last night have left no rest to my senses.

Postage, Paper And Censorship

The material facts of the postal system shaped these letters. Until the British General Post Office reforms of 1840, postage was paid by the recipient, not the sender, and the cost was calculated by distance and by the number of sheets. A letter from the Italian campaign to Paris cost roughly a day's wage for a labourer. Correspondents wrote densely, filled every margin, and sometimes turned the page ninety degrees and wrote crosswise over the first text. Napoleon did this habitually. The surviving manuscripts show the crossed lines that make transcription difficult. The published edition by the Fondation Napoléon, Lettres de Napoléon à Joséphine, includes photographs of the originals alongside the transcription. Military letters were routinely opened by the army postal service, and Napoleonic generals, including Napoleon himself, used code names for mistresses and political references to avoid interception. The letters reveal an emotional expression norm that permitted grand declarations but expected them in a masculine register of command. Napoleon does not ask, he asserts.

Accessing The Archive

The BnF has digitised a portion of the correspondence and the images are available free on Gallica, its digital platform. The physical manuscripts require a reader's card, but the digital facsimiles show the crossed writing and the paper quality that the transcriptions flatten.

The Letters And Their Physical State

John Keats wrote to Fanny Brawne between 1819 and 1820, and thirty-seven of those letters survive, held in the British Library in London and at Keats House in Hampstead. They are written in English, in Keats's late hand, on folded sheets of laid paper, sometimes with a wax seal. The convention is the Romantic love letter of the early nineteenth century, which had absorbed the emotional expressiveness of the previous generation but added a new self-consciousness about the act of writing itself. Keats writes to Fanny as my sweet love and my dearest girl, but he also theorises about love, about the imagination, and about the impossibility of fully expressing feeling in words. The letters are private, not intended for publication. They show the shift from the formal courtship letter to something closer to the modern intimate exchange. Paper was expensive. The letters are written on both sides of each sheet, with no blank margins. The ink is iron gall, which has browned over two centuries and in some places has eaten through the paper. The British Library's conservation department has stabilised the manuscripts but asks readers to use the microfilm copies for transcription.

Postal Speed And Emotional Norms

The postal system mattered here too. Keats and Brawne lived in the same city, and letters travelled by the twopenny post within London. A letter could be delivered within hours, allowing a rapid back-and-forth that the earlier generation had not had. The letters reveal an emotional expression norm that prized sincerity and spontaneity, but the letters themselves are carefully crafted. Keats revises his declarations. In one letter he writes, I have been astonished that Men could die Martyrs for religion, I have shuddered at it. I shudder at it. I could not be a Martyr for my religion, I am a Martyr for Love.

Where To Find Them

The British Library holds the largest group of these letters. The library's website provides digitised images of several sheets, including the famous one with I cannot exist without you underlined twice. Keats House in Hampstead has a smaller collection, including letters and a lock of Brawne's hair, and is open to the public. The manuscript letters there are displayed on rotation to limit light damage. The published scholarly edition is the two-volume Letters of John Keats, edited by Hyder Edward Rollins, which gives the transcription and the textual variants.

A Modern Intimate Exchange

The letters between Vita Sackville-West and Virginia Woolf, written between 1922 and 1941, are held in two places: the Berg Collection at the New York Public Library and the University of Sussex Special Collections. They are written in English, in both women's distinctive hands, on commercial letterhead and personal stationery. The convention has shifted decisively from the formal courtship letter to the modern intimate letter, with no prescribed salutation or sign-off. Woolf opens letters with Dearest Vita or My dear Vita. Sackville-West writes Darling or Dear Virginia. The emotional expression norm is one of candour, though both women were aware that the letters might be read by others. Woolf's diary records her suspicion that Sackville-West's letters were opened by her husband, Harold Nicolson. The letters show a careful dance between confession and concealment.

Paper, Ink And The Archive

The material facts are modern. The paper is machine-made, the ink is often blue-black fountain pen, and the letters are typed as often as handwritten by Sackville-West, who was a faster typist. The postal system was fast and cheap. A letter posted in London reached the recipient in the country by the next day. The Berg Collection acquired the correspondence in the 1960s, and it is one of the most heavily used collections in the library. The New York Public Library requires an appointment to read in the Berg's reading room. Readers must use the published transcription first, which is the two-volume edition of The Letters of Vita Sackville-West and Virginia Woolf, edited by Louise DeSalvo and Mitchell Leaska. The University of Sussex holds the papers that Woolf's husband Leonard deposited there after her death, including additional letters and drafts of Orlando, the novel Woolf wrote as a gift to Sackville-West. The letters reveal that the companionate marriage ideal, often dated to the mid-twentieth century, was already being lived by these two women in their friendships and their marriages. Both maintained long-term same-sex relationships alongside their marriages, and the letters document the negotiation of those arrangements with a frankness that earlier letter-writing manuals could not have sanctioned.

The Manuals That Taught Love

Between the sixteenth and nineteenth centuries, letter-writing manuals codified the conventions that the surviving letters both follow and break. The peak period for these manuals was the seventeenth to nineteenth centuries in Europe and North America. The most popular English example is John Hill's The Young Secretary's Guide, first published in 1687 and reprinted for over a century. These manuals taught the forms of address: To the Right Honourable for a peer, Dear Sir for a gentleman, My dearest only for a betrothed or a spouse. They prescribed the order of a letter: salutation, compliment, business, conclusion, signature. They warned against emotional excess. The manual is the source of the Victorian letter-writing conventions that dominate surviving archives: the use of scented paper and coloured inks, the pressing of flowers inside the sheet, and the practice of cross-writing to save paper and postage.

Postage, Literacy And The Flower Code

The Victorian era in the United Kingdom, from the 1830s to the turn of the twentieth century, saw the Postal Reform Act of 1840 introduce the penny post. This shifted the cost of postage from the recipient to the sender and made a letter affordable for a working-class correspondent for the first time. Literacy rates rose in parallel. In England and Wales, adult literacy went from roughly fifty percent in 1800 to over ninety percent by 1900. The letter became the primary medium of courtship for a wider population than ever before. The language of flowers, or floriography, peaked in the same decades. Charlotte de Latour's Le Langage des Fleurs, published in 1819, codified the meanings of specific blooms: a rosebud meant young love, a violet meant modesty, and a yellow rose meant jealousy. The manuals and the flower dictionaries together produced a coded vocabulary that allowed correspondents to express feelings that propriety forbade spelling out.

Reading The Physical Object

The Victorian love letter is therefore not a spontaneous outpouring. It is a performance of a script. The surviving letters show people working inside the script, sometimes skilfully, sometimes stiffly. The material culture of the letter, the paper, the seal, the postmark, carried meaning as much as the words did. A letter written on mourning paper, with a black border, said something about the writer's circumstances before it was opened. A seal pressed in wax carried a crest or a motto that identified the sender. The transcriptions of these letters, in scholarly editions, preserve the words but flatten the material facts. The physical object, with its crossings-out and its coffee stains, is the fuller evidence.

Paper, Scent And The Knot

The surviving Japanese love letters of the Heian period, from 794 to 1185, are as much about their wrapping as their words. The convention is documented in The Pillow Book of Sei Shōnagon and The Tale of Genji, both written in the early eleventh century. A love letter was written on paper whose colour and scent were chosen to match the occasion and the season. The paper was folded, and the letter was tied with a specific knot, or musubi, that indicated the emotional content. A loose knot might suggest a tentative courtship. A tight knot signalled a firm declaration. The recipient's first act was to read the knot before opening the sheet. The ink was made from soot, the brush was a calligraphy brush, and the handwriting itself was read as evidence of character. A poorly formed character could end a courtship before the words were read.

Script, Response And Survival

The language was classical Japanese, written in the phonetic script called kana, which was the medium of women's writing. Men typically wrote in Chinese characters. The boundary between the two scripts was itself a statement about intimacy. The expected response time was before dawn. A letter received at night demanded a reply by morning, and a delay was read as rejection. The reply was written on the same paper if the recipient was willing, or on a new sheet of matching quality if the recipient wished to continue without committing. The material facts are severe for the modern reader. Paper was handmade from mulberry fibre, ink was perishable, and almost no Heian love letters survive as physical objects. The evidence for the conventions comes from the fictional and documentary literature, not from an archive of manuscripts. The closest surviving artefacts are the poetry anthologies, such as the Kokin Wakashū, which preserve the poems that accompanied the letters. The letters themselves were often destroyed after reading, a deliberate act that the literature treats as a sign of discretion. The published English translation of The Tale of Genji, by Royall Tyler, includes the most complete reconstruction of the letter-and-knot system in a Western language.

Allusion Instead Of Declaration

The Chinese love letter tradition, which begins in the Tang dynasty (618-907) and continues through the imperial period, is built on poetry and allusion rather than personal narrative. A courtship letter in classical Chinese did not say I love you. It quoted a poem, deployed a parallel couplet, and alluded to a classical text that carried the emotional weight. The material facts are the medium of brush and ink on paper, the formal structure of the letter, and the use of the classical language, which was distinct from the spoken vernacular. The literary references did the expressing. A line from the Book of Songs, the oldest Chinese poetry collection, could signal a lover's longing without the writer having to state it.

Surviving Evidence And Marginalia

The convention is documented in the surviving letters of the Tang and Song dynasties, though the great majority of private correspondence was destroyed in the many wars and purges of the following centuries. The most famous surviving example is the exchange between the Southern Song poet Li Qingzhao and her husband Zhao Mingcheng, written in the early twelfth century. The couple's letters and their joint collection of antiquities are described in Li Qingzhao's own memoir, the Afterword to the Record of Metal and Stone. The letters themselves are lost, but the memoir quotes the terms of their intimacy. The couple wrote notes to each other in the margins of books, and those marginalia, called shouli, functioned as love letters. The allusion tradition meant that a writer could express forbidden or impossible love through the voice of an ancient poet. The surviving poetry of the period is full of such indirection. The language of flowers, the parallel couplet, and the literary allusion are all still taught in Chinese schools. The tradition has a continuity that the European letter-writing manuals do not.

Where To See The Manuscripts

The archive for the surviving manuscript material is the National Library of China in Beijing, which holds a small number of Tang and Song dynasty personal letters. The request procedure is bureaucratic and requires a research affiliation. To see the tradition in a physical form, visit the Palace Museum in Taipei. It holds the album letters of the Qing dynasty, including love letters written between the Kangxi and Qianlong emperors and their consorts. These are written in Chinese on imperial paper, with the emperor's vermilion seal. They show the same conventions of allusion and indirection operating at the highest level of the state.

• Period: Tang dynasty (618-907) onward
• Convention: Poetry, parallel couplets, classical allusion
• Medium: Brush and ink on paper
• Surviving example: Li Qingzhao and Zhao Mingcheng, early 12th century (described in her memoir)
• Archive: National Library of China; Palace Museum, Taipei

Six Letters, Six Different Scripts

The six examples above are arranged in chronological order for a reason. They show that emotional expression norms are not universal but historical and regional products. The Sumerian song treats love as a state ritual. The Abelard and Héloïse exchange treats it as a theological problem. Napoleon's letters treat it as a military campaign. Keats's letters treat it as a matter of life and death. Sackville-West and Woolf treat it as a private negotiation. The Heian and Chinese traditions treat it as a coded performance. None of these is a transparent record of inner feeling. Each is a document shaped by the material culture of its time: the cost of paper, the speed of the post, the literacy rate, the censorship regime, and the legal status of the writer.

The Shift To Companionate Marriage

The nineteenth-century shift to companionate marriage, in which the union is based on emotional fulfilment rather than economic or practical necessity, is visible in the letters only as a late development. The earlier letters are explicitly about arranged marriage, courtly love conventions, and the social function of marriage as an alliance between families. The Victorian letter-writing manuals, with their insistence on proper forms of address, were not dead formalism. They were the scaffolding that allowed people to express intense feeling in a society that had no other sanctioned vocabulary for it. The historical linguistics of the letters is also revealing. The salutations change from my lord to my dear to darling over three centuries. The change tracks the shift from hierarchical to egalitarian marriage. The censorship that shaped wartime correspondence produced letters that are more oblique than the private ones. The suppression of certain words and phrases is itself evidence of what was considered dangerous to say. Treat these letters as a control group. They show that I love you is not a universal utterance but a historically specific one. The way you write a love letter now, short, direct, unadorned, is as much a convention as the crossed writing and scented paper of the Victorians.

Reader's Cards And Appointments

If you want to see any of these letters in the flesh, make an appointment. The British Library, the Bibliothèque nationale de France, and the New York Public Library all require reader's cards. The application process takes at least a few days. For the British Library, bring identification and proof of address, and apply online before you travel. The manuscripts reading room is on the third floor. For the BnF, the application for a reader's card is made at the entrance in person, but the manuscript reading room requires a research justification. The Napoleon letters are in the Richelieu site, not the newer François-Mitterrand building. For the Berg Collection at the New York Public Library, the reading room is on the fifth floor of the Stephen A. Schwarzman Building. The collection requires a letter of introduction if you are not an academic. The staff can supply the format on request.

Why Digital Is Better

The libraries all have digitisation programmes. For most purposes the digital facsimiles are superior to the physical manuscripts. They can be enlarged. They show the ink corrosion that is invisible to the naked eye. They do not require a reading room appointment at all. If you are not doing original research, the digitised images on Gallica, the British Library's catalogue, and the NYPL's digital collections are the better route. The failure case is the visitor who turns up at a library entrance without a card or a letter of introduction and is turned away. This happens weekly. The reading rooms are reserved for researchers, not tourists. The one exception is Keats House in Hampstead, which displays a rotating selection of the Keats letters in a public gallery with no appointment required. The display changes seasonally, so check the website before you go. The cost of a reader's card is free in all three libraries. The opportunity cost of being turned away is half a day of your trip. Book the appointment before you book your transport. The library websites all have an online booking system, and the manuscript reading rooms fill up days in advance during the summer and the academic year.

What is the oldest surviving love letter? The oldest known love text is the Sumerian Love Song of Shu-Sin, a clay tablet from around 2000 BCE, held in the Istanbul Archaeology Museums. It is a liturgical poem rather than a private letter.

Where are the Napoleon letters to Joséphine? The majority are held at the Bibliothèque nationale de France in Paris, with a small number in private collections. The BnF has digitised most of them on Gallica.

Did Victorians really cross-write their letters? Yes. Because postage was paid by weight until 1840 and by the recipient afterwards, correspondents turned the page ninety degrees and wrote over the first text. Napoleon did this habitually, and the Keats letters show the practice as well.

Can I see the Woolf letters without a research card? No. The Berg Collection at the New York Public Library requires an appointment and a letter of introduction for non-academics. The published edition by DeSalvo and Leaska is the accessible route.

Are any Heian period love letters still in existence? Essentially none. The conventions are known from The Tale of Genji and The Pillow Book, but the letters themselves were typically destroyed after reading. The surviving evidence is literary rather than archival.
