El Rancho Vegas was the first resort to open on the Las Vegas Strip in 1941, but it wasn't until the Flamingo opened in 1946, which gangster Bugsy Siegel financed with the help of fellow mob boss Meyer Lansky, that the mafias had any control over the hotels and clubs in Las Vegas.
In the 1950s, live entertainment began to draw tourists to Las Vegas. Elvis Presley, Frank Sinatra, Bing Crosby and other movie and music stars cemented their place in the city's history.
