Henry Addington, 1st Viscount Sidmouth
(30 May 1757 – 15 February 1844)
Henry Addington, was a British statesman who served as Prime Minister from 1801 to 1804. He is best known for obtaining the Treaty of Amiens in 1802, an unfavourable peace with Napoleonic France which marked the end of the Second Coalition during the French Revolutionary Wars. When that treaty broke down he resumed the war but he was without allies and conducted a relatively weak defensive war, ahead of what would become the War of the Third Coalition. He was forced from office in favour of William Pitt the Younger, who had preceded Addington as Prime Minister.
He returned to government again as Lord President in March 1812, and, in June of the same year, became Home Secretary. As Home Secretary, Sidmouth countered revolutionary opposition, being responsible for the temporary suspension of habeas corpus in 1817 and the passage of the Six Acts in 1819. His tenure also saw the Peterloo Massacre of 1819. Sidmouth left office in 1822, succeeded as Home Secretary by Sir Robert Peel, but remained in the Cabinet as Minister without Portfolio for the next two years, fruitlessly opposing British recognition of the South American republics. He remained active in the House of Lords for the next few years, making his final speech in opposition to Catholic Emancipation in 1829 and casting his final vote against the Reform Act 1832.
