Nevada legalized gambling on March 19, 1931, when Governor Fred Balzar signed Assembly Bill 98 into law. This historic decision made Nevada the first state in the United States to legalize most forms of gambling.

The legalization came during the Great Depression, as Nevada sought new ways to boost its struggling economy. The bill, introduced by Phil Tobin, transformed Nevada's gambling landscape from underground operations to a legitimate, regulated industry.

Before 1931, gambling existed in Nevada but operated illegally. The state had previously banned all gambling activities in 1909, pushing the industry underground. However, illegal gambling continued to thrive throughout the 1920s, particularly in Las Vegas and Reno.

The 1931 law specifically legalized games including:

- Card games
- Slot machines
- Dice games
- Horse race betting
- Sports betting

This legislation laid the foundation for Nevada's modern gaming industry. Las Vegas, in particular, experienced rapid growth following the legalization, especially after the construction of the Hoover Dam brought thousands of workers to the area.

The tax revenue from legal gambling helped Nevada weather the Great Depression better than many other states. In the first year after legalization, the state collected $3.9 million in gambling taxes, equivalent to about $69 million in today's money.

Important changes followed the initial legalization:

- 1945: The Nevada Tax Commission began overseeing gambling
- 1955: The Gaming Control Board was established
- 1959: The Nevada Gaming Commission was created

Today, Nevada remains America's gambling capital, with Las Vegas generating billions in annual revenue. The 1931 decision to legalize gambling has shaped the state's identity and economy for nearly a century, creating a model that other states would later follow.

The success of Nevada's gambling industry has influenced many other states to legalize various forms of gambling, though none have achieved the same level of gaming prominence as Nevada. This pioneering move in 1931 established Nevada as America's premier gambling destination, a position it continues to hold today.
