Eureka was founded as a town in 1850 and incorporated as a city in 1874. Located on the remote northwestern coast of California, Eureka was the region's major port of entry by water in the 19th century before the construction of good access by land, and rose to historical prominence as the major social, political and economic center of the region. "Eureka" is a Greek expression and a popular mining term meaning "I have found it."
