Occupy London was a political movement in London, England, and part of the international Occupy movement. While some media described it as an "anti-capitalist" movement, in the statement written and endorsed by consensus by the Occupy assembly in the first two days of the occupation, occupiers defined themselves as a movement working to create alternatives to an "unjust and undemocratic" system. A second statement endorsed the following day called for "real global democracy". Due to a pre-emptive injunction, the protesters were prevented from their original aim to camp outside the London Stock Exchange. A camp was set up nearby next to St Paul's Cathedral. On 18 January 2012, Mr Justice Lindblom granted an injunction against continuation of the protest but the protesters remained in place pending an appeal. The appeal was refused on 22 February, and just past midnight on 28 February, bailiffs supported by City of London Police began to remove the tents.

Paternoster Square is a former historic square, renamed from Newgate Market c. 1872, and now a post-war urban redevelopment, owned by the Mitsubishi Estate, next to St Paul's Cathedral in the City of London. The area, previously named Paternoster Row, after the street of the same name, once centre of the London publishing trade, was devastated by aerial bombardment in The Blitz during World War II. It is now the location of the London Stock Exchange which relocated there from Threadneedle Street in 2004. It is also the location of investment banks such as Goldman Sachs, Merrill and Nomura Securities, and of fund manager Fidelity Investments. The square itself, i.e. the plaza, is privately owned public space. In 2004, Christopher Wren's 1669 Temple Bar Gate was re-erected here as an entrance way to the plaza.
