The Barbary Coast was born during the California Gold Rush of 1849, when the population of San Francisco was growing at an exponential rate due to the rapid influx of tens of thousands of miners trying to find gold. The early decades of the Barbary Coast were marred by persistent lawlessness, gambling, administrative graft, vigilante justice, and prostitution; however with the passage of time, the city's government gained strength and competence, and the Barbary Coast's maturing entertainment scene of dance halls and jazz clubs influenced American culture. The Barbary Coast's century-long evolution passed through many substantial incarnations due to the city's rapid cultural development during the transition to the 20th century. Its former location now is overlapped by Chinatown, North Beach, and Jackson Square.
