In 1900, only 22 people lived in Las Vegas. In fact, it wasn’t until 1930 when President Herbert Hoover–in the midst of the Great Depression–commissioned the Boulder Dam (renamed the Hoover Dam), that people began flooding to the city. Though a small but dedicated gambling community had existed for years, the Nevada state legislature only legalized local gambling in 1931. After the law was passed, casinos and hotels began popping up along Fremont Street, marking the birth of today’s beloved Strip.
These days more than 39 million people visit Las Vegas each year.
