Who organized the first commercial tourism in the world in 1841?

The world's first commercial tour was organized by the British travel agency Thomas Cook & Son in 1841. At that time, Thomas Cook & Son organized a rail tour from Liverpool, England, to Yorkshire, which is considered to be the world's first commercial tour. That tour was attended by 570 passengers, who paid a tour fee of one shilling per person, which included tickets and lunch. The tour was so successful that it prompted Thomas Cook & Son to establish more travel agencies in the UK and other countries, making an important contribution to the development of the tourism industry.
