The earliest casinos were established in Italy, which was the home of the first Ridotto in 1638. Casinos were popular in these countries because it was a way for people to have fun without getting into trouble. In the 19th century, casinos became more prevalent as France and Italy began to build them.
In the 17th century, the first casinos were more of a place for people to gamble than for them to have fun and socialize. Despite the long history of gambling, casinos first started in the 16th century, but did not gain popularity until much later.
