The history of Antioch, one of California's oldest cities, began during the Gold Rush era. The city was founded by two minister brothers, William and Joseph Smith, who purchased land here in 1849. Initially, the settlement was named Smith's Landing. The city received its modern name on July 4, 1851, during a town picnic when residents, at the suggestion of William Smith, decided to name it after the biblical city of Antioch, where followers of Christ were first called Christians. The name was also chosen in memory of his brother Joseph, who had passed away a year earlier.
A key factor in the city's growth was its strategic location on the San Joaquin River. Deep-water access allowed ships to dock year-round, turning Antioch into a vital transportation and commercial hub for farmers and prospectors. The port facilitated active trade in agricultural products with San Francisco. Antioch was officially incorporated as a city in 1872.
Antioch's early economy was closely tied to the region's natural resources. Beyond agriculture, mining provided a massive boost to development. In 1859, significant coal deposits were discovered in the hills south of the city, leading to the creation of the Mount Diablo coal field, the largest in California. This led to the emergence of several mining towns and the construction of a railroad to transport coal through Antioch to the river. For a short time, the city also hosted a copper smelting plant, brick kilns, and pottery workshops, illustrating its early industrial importance.
