Henry Addington
British Tory prime minister and Home Secretary.
Henry Addington, 1st Viscount Sidmouth, was a British Tory politician who held two key roles: Speaker of the House of Commons from 1789 to 1801, and then Prime Minister from 1801 to 1804. His time as prime minister is most remembered for the Treaty of Amiens in 1802, a peace deal with Napoleonic France that was widely seen as unfavorable to Britain. The treaty ended the Second Coalition during the French Revolutionary Wars. When the peace fell apart, Addington went back to war but without any allies, fighting a largely defensive campaign that set the stage for the War of the Third Coalition. His administration also saw the first Kandyan War, which ended in a British defeat. He was eventually pushed out of office, making way for William Pitt the Younger, the very man he had replaced. Later, as Home Secretary from 1812 to 1822, he became known for a harsh, reactionary campaign against people pushing for democratic reforms. That ten-year stretch makes him the longest continuously serving Home Secretary since the office was created in 1782.
Addington was born to Anthony Addington, who was physician to Pitt the Elder, and Mary Addington, daughter of the headmaster of Reading School. Thanks to his father’s connections, he grew up as a childhood friend of William Pitt the Younger. He was educated at Reading School, Winchester College, and Brasenose College, Oxford, before studying law at Lincoln’s Inn. In 1781, he married Ursula Mary Hammond, who brought an annual income of £1,000 to the marriage. They had eight children, six of whom lived to adulthood. After Ursula died in 1811, he married a widow named Marianne Townsend, daughter of William Scott, 1st Baron Stowell.
Addington entered the House of Commons in 1784 as a member for Devizes, and became Speaker in 1789. In March 1801, Pitt resigned—officially over King George III’s refusal to lift political restrictions on Irish Catholics, but also due to poor health, war failures, economic collapse, famine-driven social unrest, and deep cabinet divisions. Both Pitt and the King pushed Addington to take over as prime minister, despite his own reluctance and failed attempts to reconcile the two.
Foreign policy defined Addington’s premiership. Some historians have been harsh, calling it ignorant and indifferent to Britain’s needs. Others, like Thomas Goldsmith, argue that Addington and his foreign secretary, Lord Hawk

Lore & Background
Henry Addington was the son of Anthony Addington, Pitt the Elder's physician, and Mary Addington. As a consequence of his father's position, he was a childhood friend of William Pitt the Younger. He studied at Reading School, Winchester College, and Brasenose College, Oxford, and then studied law at Lincoln's Inn. He married Ursula Mary Hammond in 1781; she brought an income of £1,000 a year into the marriage. The couple had eight children, of whom six survived to adulthood. After Ursula died in 1811, Addington married a widow, Marianne Townsend, daughter of William Scott, 1st Baron Stowell.
Addington was elected to the House of Commons in 1784 as one of the Members of Parliament for Devizes, and became Speaker of the House of Commons in 1789. In March 1801, William Pitt the Younger resigned, and both Pitt and King George III insisted that Addington take over as prime minister, despite his own objections. His administration secured the Treaty of Amiens in 1802, but when that treaty broke down, Addington resumed the war without allies. He was forced from office in 1804 in favour of Pitt. Addington later served as Home Secretary from 1812 to 1822, where he countered revolutionary opposition with harsh measures, including the temporary suspension of habeas corpus in 1817 and the passage of the Six Acts in 1819.
Reader's Guide
Henry Addington's significance lies in his role as a transitional prime minister during a critical period of the Napoleonic Wars. His negotiation of the Treaty of Amiens, though unfavourable, provided a necessary respite for a Britain facing financial collapse, famine, and social unrest. His subsequent conduct of the war, while criticized as lacklustre, was constrained by the lack of allies and focused on defence, strengthening British forces and fortifications. As Home Secretary, his reactionary policies against democratic reformers, including the suspension of habeas corpus and the Six Acts, marked a period of intense domestic repression. Addington's legacy is mixed: he is remembered for the unpopular peace of Amiens and for his hardline stance at home, but also for his administrative reforms and his role in maintaining political stability during turbulent times. His inability to manage a parliamentary majority led to his downfall as prime minister, but he remained a significant political figure, influencing cabinets and opposing Catholic Emancipation until his final years.
