Nevada legalized gambling on March 19, 1931, when Governor Fred Balzar signed Assembly Bill 98 into law. This landmark legislation made Nevada the first state in the U.S. to legalize most forms of gambling, including casino games and sports betting.

The decision to legalize gambling came during the Great Depression, when Nevada was seeking new ways to boost its economy. Phil Tobin, an assemblyman from Humboldt County, introduced the bill, which became known as the "Wide Open Gambling Bill."

Prior to 1931, gambling existed in Nevada but operated in a legal gray area. The state had previously banned gaming in 1909, though some illegal operations continued throughout the 1920s. The 1931 legislation brought gambling into the mainstream and established a framework for regulation.

Key aspects of the 1931 legislation included:

Legalization of most forms of gambling
Implementation of a state licensing system
Creation of tax revenue streams from gambling operations
Establishment of basic regulatory oversight

The impact of this legislation was not immediate. Las Vegas, now famous for its casinos, didn't see significant growth until after World War II. The first major casino-hotel on what would become the Las Vegas Strip, the El Rancho Vegas, opened in 1941.

The 1931 law remains the foundation of Nevada's gambling industry today, though it has been amended numerous times to adapt to changing times and technologies. This decision transformed Nevada into America's gambling capital and created a model for other states' gambling legislation.

The legalization of gambling fundamentally changed Nevada's economy. Today, the gaming industry generates billions in revenue annually and employs hundreds of thousands of people across the state. It's worth noting that Nevada remained the only state with legal casino gambling until New Jersey legalized gambling in Atlantic City in 1976.

Modern Nevada gambling regulations stem from this original legislation, though they've evolved significantly to include strict oversight, consumer protections, and sophisticated regulatory frameworks. The Nevada Gaming Control Board, established in 1955, now oversees all gambling operations in the state.

This pioneering move in 1931 established Nevada's reputation as America's gambling capital, a distinction it maintains nearly a century later. The decision to legalize gambling during the Great Depression proved to be one of the most significant economic decisions in the state's history.
