On March 17, 1931, Nevada legalized casino gambling. The move came during the Great Depression as a way to attract tourism and create jobs. Over time, cities like Las Vegas and Reno grew into major gambling and entertainment centers. Casinos brought new economic activity and large-scale resort development. However, they also raised questions about regulation, crime, and economic dependence on gaming. Nevada’s decision reshaped its identity and became a model observed by other jurisdictions considering legalized gambling.
