The Lord Mayor's Show is one of the best-known annual events in London as well as one of the longest-established, dating back to the 13th century. A new lord mayor is appointed every year, and the public parade that takes place as their inauguration ceremony reflects that this was once one of the most prominent offices in England and subsequently the United Kingdom.

In 1747, the Lord Mayor went to the City of Westminster on a barge via the River Thames. These were the original parade floats.

A parade is a procession of people, usually organized along a street, often in costume, and often accompanied by marching bands, floats, or sometimes large balloons. Parades are held for a wide range of reasons, but are usually celebrations of some kind.
