Before the construction of London's bridges and the Underground, the River Thames had served as a major thoroughfare for centuries. Attempts to regulate the transport of passengers and goods began in 1197, when King Richard I sold the Crown's rights over the Thames to the City of London Corporation, which then attempted to license boats on the river. In 1510 Henry VIII granted a licence to watermen that gave exclusive rights to carry passengers on the river, and in 1555 an Act of Parliament set up the Company of Watermen and Lightermen to control traffic on the Thames.
