Las Vegas, officially the City of Las Vegas and often known as simply Vegas, is a city in the United States, the most populous city in the state of Nevada, the county seat of Clark County, and the city proper of the Las Vegas Valley. Las Vegas is an internationally renowned major resort city known primarily for gambling, shopping, fine dining and nightlife and is the leading financial and cultural center for Southern Nevada.
Perhaps the earliest visitors to the Las Vegas area were nomadic Paleo-Indians, who traveled here 10,000 years ago, leaving behind petroglyphs. Anasazi and Paiute tribes followed at least 2,000 years ago. A young Mexican scout named Rafael Rivera is credited as the first non-Native American to encounter the valley, in 1829. Trader Antonio Armijo led a 60-man party along the Spanish Trail to Los Angeles, California in 1829. The area was named Las Vegas, which is Spanish for "the meadows", as it featured abundant wild grasses, as well as desert spring waters for westward travelers. The year 1844 marked the arrival of John C. Fremont, whose writings helped lure pioneers to the area. Downtown Las Vegas' Fremont Street is named after him.
