Nevada legalized wide-open gambling in the depths of the Depression
On this day · 19 March 1931
A struggling desert state bet on legal casinos in 1931 — and quietly set Las Vegas on the road to becoming a global capital of play.
On March 19, 1931, Governor Fred Balzar signed Assembly Bill 98, legalizing wide-open casino gambling across Nevada. The bill came from an unlikely source: Phil Tobin, a rancher and freshman assemblyman from rural Humboldt County, not a casino lobbyist or city machine.
The timing was no accident. The Great Depression had gutted Nevada’s mining economy and sent residents fleeing. Rather than ban the gambling that already flourished underground, lawmakers chose to tax and regulate it, hoping to raise revenue and lure visitors. The same year, the state also slashed its residency requirement for divorce to six weeks.
At the time, the move drew barely a mention in local newspapers.
Few foresaw what it would become. The transformation of dusty Las Vegas into an “American Monte Carlo” was slowed by the Depression and accelerated only after World War II. But the legal foundation laid in 1931 made the modern casino industry — and the city’s neon future — possible.
