Horatio Walpole, 4th Earl of Orford (; 24 September 1717 – 2 March 1797), better known as Horace Walpole, was a British Whig politician, writer, historian and antiquarian.

He had Strawberry Hill House built in Twickenham, southwest London, reviving the Gothic style some decades before his Victorian successors. His literary reputation rests on the first Gothic novel, The Castle of Otranto (1764), and his Letters, which are of significant social and political interest. They have been published by Yale University Press in 48 volumes. In 2017, a volume of Walpole's selected letters was published.Selected Letters, edited and introduced by Stephen Clarke. New York: Everyman's Library, Alfred A. Knopf, 2017.

The youngest son of the first British prime minister, Sir Robert Walpole, 1st Earl of Orford, he became the 4th and last Earl of Orford of the second creation on his nephew's death in 1791.

Early life: 1717–1739

Walpole was born in London, the youngest son of British Prime Minister Sir Robert Walpole and his wife, Catherine. Like his father, he received early education in Bexley; in part under Edward Weston. He was also educated at Eton College and King's College, Cambridge.

Walpole's first friends were probably his cousins Francis and Henry Conway, to whom he became strongly attached, especially Henry. At Eton he formed a schoolboy confederacy, the "Triumvirate", with Charles Lyttelton (later an antiquary and bishop) and George Montagu (later a member of parliament and Private Secretary to Lord North). More important were another group of friends dubbed the "Quadruple Alliance": Walpole, Thomas Gray, Richard West, and Thomas Ashton.

At Cambridge, Walpole came under the influence of Conyers Middleton, an unorthodox theologian. Walpole came to accept the sceptical nature of Middleton's attitude to some essential Christian doctrines for the rest of his life, including a hatred of superstition and bigotry even though he was a nominal Anglican. Ceasing to reside at Cambridge at the end of 1738, Walpole left without taking a degree.

In 1737, Walpole's mother died. According to one biographer, his love for his mother "was the most powerful emotion of his entire life ... the whole of his psychological history was dominated by it". Walpole did not have any serious relationships with women; he has been called "a natural celibate".

His sexual orientation has been the subject of speculation. He never married, engaging in a succession of unconsummated flirtations with unmarriageable women, and counted among his close friends a number of women such as Anne Seymour Damer and Mary Berry named by a number of sources as lesbian.

Many contemporaries described him as effeminate (one political opponent called him "a hermaphrodite horse"). Biographers, such as W. S. Lewis, Brian Fothergill, and Robert Wyndham Ketton-Cremer, interpreted Walpole as asexual.

Walpole's father secured for him three sinecures which afforded him an income: in 1737 he was appointed Inspector of the Imports and Exports in the Custom House, which he resigned to become Usher of the Exchequer, which gave him at first £3900 per annum but this increased over the years. Upon coming of age he became Comptroller of the Pipe and Clerk of the Estreats which gave him an income of £300 per annum. Walpole decided to go travelling with Thomas Gray and wrote a will in which he left Gray all his belongings.

In 1744, he wrote in a letter to Conway that these offices gave him nearly £2,000 per annum; after 1745 when he was appointed Collectorship of Customs, his total income from these offices was around £3,400 per annum.

Grand Tour: 1739–1741

Walpole went on the Grand Tour with Gray, but as Walpole recalled in later life: "We had not got to Calais before Gray was dissatisfied, for I was a boy, and he, though infinitely more a man, was not enough to make allowances".

They left Dover on 29 March and arrived at Calais later that day. They then travelled through Boulogne, Amiens and Saint-Denis, arriving at Paris on 4 April. Here they met many aristocratic Englishmen. In early June they left Paris for Reims, then in September going to Dijon, Lyon, Dauphiné, Savoy, Aix-les-Bains, Geneva, and then back to Lyon.

In October they left for Italy, arriving in Turin in November, then going to Genoa, Piacenza, Parma, Reggio, Modena, Bologna, and in December arriving at Florence. Here he struck up a friendship with Horace Mann, an assistant to the British Minister at the Court of Tuscany. In Florence he also wrote Epistle from Florence to Thomas Ashton, Esq., Tutor to the Earl of Plymouth, a mixture of Whig history and Middleton's teachings. In February 1740, Walpole and Gray left for Rome with the intention of witnessing the papal conclave upon the death of Pope Clement XII but never saw it. Walpole wanted to attend fashionable parties and Gray wanted to visit antiquities. At social occasions in Rome, he saw the Old Pretender, James Francis Edward Stuart, and his two sons, Charles Edward Stuart and Henry Stuart, although there is no record of them conversing.

Walpole and Gray returned to Florence in July. However, Gray disliked the idleness of Florence as compared to the educational pursuits in Rome, and animosity grew between them, eventually leading to an end to their friendship. On their way back to England they had a furious argument, although it is unknown what it was about. Gray went to Venice, leaving Walpole at Reggio. In later life Walpole admitted that the fault lay primarily with himself:

Walpole then visited Venice, Genoa, Antibes, Toulon, Marseille, Aix, Montpellier, Toulouse, Orléans and Paris. He returned to England on 12 September 1741, reaching London on the 14th.

Early parliamentary career: 1741–1754 By 1735, Walpole was a student at King's College, Cambridge. He had long periods of absence from the college, often returning to Norwich to live at Houghton Hall, in Norfolk. Interested in local politics, he and the "wealthy" Mayor of Norwich, Philip Meadows, encouraged local merchant Thomas Vere to run for a seat in Parliament "in the Whig interest" with Vere becoming the MP for Norwich in 1735.

At the 1741 general election Walpole was elected as a Member of Parliament for the rotten borough of Callington, Cornwall. He held this seat for thirteen years although he never visited Callington. Walpole entered Parliament shortly before his father's fall from power. In December 1741 the Opposition won its first majority vote in the Commons for twenty years. In January 1742, Walpole's government was still struggling in Parliament, although by the end of the month, Horace and other family members had successfully urged the prime minister to resign after a parliamentary defeat. Walpole's philosophy mirrored that of Edmund Burke, who was his contemporary. He was a classical liberal on issues such as slavery and the American Revolution.

Walpole delivered his maiden speech on 19 March against the successful motion that a Secret Committee be set up to enquire into Sir Robert Walpole's last ten years as prime minister. For the next three years, Walpole spent most of his time with his father at his country house Houghton Hall in Norfolk. His father died in 1745 and left Walpole the remainder of the lease of his house in Arlington Street, London; £5,000 in cash; and the office of Collector of the Customs (worth £1,000 per annum). However, he had died in debt, the total of which was in between £40,000 and £50,000.

In late 1745 Walpole and Gray resumed their friendship. Also that year the Jacobite Rising began. The position of Walpole was the fruit of his father's support for the Hanoverian dynasty and he knew that he was in danger: "Now comes the Pretender's boy, and promises all my comfortable apartments in the Exchequer and Custom House to some forlorn Irish peer, who chooses to remove his pride and poverty out of some large old unfurnished gallery at St. Germain's. Why really, Mr. Montagu, this is not pleasant! I shall wonderfully dislike being a loyal sufferer in a threadbare coat, and shivering in an antechamber at Hanover, or reduced to teach Latin and English to the young princes at Copenhagen".

In November 1749, Walpole was robbed at gunpoint by notorious highwaymen James MacLaine and William Plunkett. He wrote of the event: "One night, in the beginning of November 1749, as I was returning from Holland House by moonlight, about ten o'clock, I was attacked by two highwaymen in Hyde Park, and the pistol of one of them going off accidentally, raised the skin under my eye, left some marks of shot in my face, and stunned me. The ball went through the top of the chariot, and if I had sat an inch nearer to the left side, must have gone through my head."Horace Walpole, recited in article 'Tyburn and Tyburnia', Old and New London, Volume 5 (Cassell Petter and Galpin, London 1878), pp. 188-203 (British History Online).'Letters nos. 310-314, to Sir Horace Mann', in P.

Strawberry Hill

Walpole's lasting architectural creation is Strawberry Hill, the home he built from 1749 onward in Twickenham, southwest of London, which at the time overlooked the Thames. Here he revived the Gothic style many decades before his Victorian successors. Derided thereafter by his friends as "The Abbot of Strawberry", this fanciful neo-Gothic concoction began a new architectural trend. Long-connected with the Blue Stockings Society, Walpole played host to its members and associates at Strawberry Hill, including Anna Laetitia Barbauld in 1774.

Later parliamentary career: 1754–1768

In the House of Commons, Walpole represented one of the many rotten boroughs, Castle Rising, which consisted of underlying freeholds in four villages near Kings Lynn, Norfolk, from 1754 until 1757. At his home, he hung a copy of the warrant for the execution of King Charles I with the inscription "Major Charta" and wrote of "the least bad of all murders, that of a King". In 1756 he wrote:

Walpole worried that while his fellow Whigs fought amongst themselves, the Tories were gaining power, the result of which would be England delivered to an unlimited, absolute monarchy, "that authority, that torrent which I should in vain extend a feeble arm to stem".

In 1757, he wrote the anonymous pamphlet A Letter from Xo Ho, a Chinese Philosopher at London, to his Friend Lien Chi at Peking, the first of his works to be widely reviewed.

In early 1757, old Horace Walpole of Wolterton died and was succeeded in the peerage by his son, who was then an MP for King's Lynn, thereby creating a vacancy. The electors of King's Lynn did not wish to be represented by a stranger and instead wanted someone with a connection to the Walpole family. The new Lord Walpole, therefore, wrote to his cousin requesting that he stand for the seat, saying his friends "were all unanimously of opinion that you were the only person who from your near affinity to my grandfather, whose name is still in the greatest veneration, and your own known personal abilities and qualifications, could stand in the gap on this occasion and prevent opposition and expense and perhaps disgrace to the family".

In early 1757, Walpole was out of Parliament after vacating Castle Rising until his election that year to King's Lynn, a seat he would hold until his retirement from the Commons in 1768.

Walpole became a prominent opponent of the 1757 decision to execute Admiral John Byng.

Later life: 1768–1788

Without a seat in Parliament, Walpole recognised his limitations as to political influence.

He wrote to Mann critical of the activities of the East India Company on 13 July 1773:
