The Story of London is to be told in a month of jousting, flotillas, fencing and falconry in June.
History buff Boris Johnson announced the season of celebrations of the city's history at Hampton Court Palace on Friday, promising the costs would not exceed £150,000 - mostly for communication and presentation of the various programmes. He said: "London is a collossus on the world stage. I'm very proud to start the celebrations for the story of London which will be a showpiece for the whole world."
"Ever since the Romans came here and established London as a great city it has been a kaleidoscope of different people and trades and creative energy. We are going to tell the stories of the people who made London."
A group of musicians and singers - "The Clerks" - played Medieval songs to the 50 press and television reporters from all over the world inside the Palace and before Munira Mirza, Director for Cultural Policy, said: "We want to help support the types of events that showcase the brilliance of London, its history, and society.
"With the Story of London we will look at London through many different lenses, and this season aims to bring all Londoners together in celebration."
"When you look back at how London began, with its dark and misty and unpromising beginning, who could have thought it would eclipse Athens, Paris and even Rome in its ability to adapt and re-invent itself generation after generation."
Mr Johnson and Ms Mirza explained how the celebrations would include a 60s day in Carnaby Street, walking tours all over London and Tudor tournaments in Richmond and at the Tower of London.
The Mayor hailed the series of events as deliberately going against the gloom of recession, and added: "We should not talk ourselves into a deeper downturn than we deserve. I see people resisting the downturn, and really there is a boom in some areas of the economy like theatre and entertainment and museums that we didn't expect. "
