Hyde Park is one of the largest parks in London, and one of the Royal Parks of London, famous for its Speakers' Corner.

The park was the site of the Great Exhibition of 1851, for which the Crystal Palace was designed by Joseph Paxton. The park has become a traditional location for mass demonstrations. The Chartists, the Reform League, the Suffragettes, and the Stop the War Coalition have all held protests in the park. Many protesters on the Liberty and Livelihood March in 2002 started their march from Hyde Park. On 20 July 1982 in the Hyde Park and Regents Park bombings, two bombs linked to the Provisional Irish Republican Army caused the death of eight members of the Household Cavalry and the Royal Green Jackets and seven horses.
