Antioch's History: A Look Back
Early Days: From Marsh's Landing to Antioch (1850s-1900s)
Antioch is one of California's oldest towns. In 1848, John Marsh built a landing on the San Joaquin River. This spot, called Marsh's Landing, was a busy shipping point for his huge ranch. Ships could dock there all year round.
In 1850, two brothers, William and Joseph Smith, started a town nearby. They named it Smith's Landing. A year later, a minister convinced people to rename it Antioch, after a city in the Bible.
Around 1859, coal was found in the hills south of Antioch. Coal mining became a major business, leading to new towns like Nortonville and Black Diamond. This boosted Antioch's economy. Later, copper was discovered in 1863, and a smelting plant was built. However, the copper boom didn't last. Oil was also drilled for in 1865, but not enough was found to be profitable.
The Antioch Post Office opened in 1851. It closed and reopened a few times before staying open continuously since 1863. Antioch officially became a city in 1872.
The Antioch Ledger newspaper started on March 10, 1870. Its first issue was small and only reported on a women's suffrage meeting. The Ledger later joined with the Contra Costa Times and stopped printing in 2005.
Modern Antioch: Growth and Change
In the mid-1950s, a company in Antioch invented a way to put wax coatings on cardboard. This led to the first milk, juice, and ice cream cartons, making Antioch known as "the home of the milk carton."
Today, Antioch is mostly a "bedroom community." This means many adults live there but work in bigger cities like Oakland and San Francisco. The city has grown a lot in the last 30 years. More people move to Antioch as housing prices in the Bay Area increase.
In 2012, the city tried to add a 678-acre area of land, including a power plant, to its city limits.

The Antioch Dunes National Wildlife Refuge was created in 1980. It was the first national wildlife refuge made to protect endangered plants and insects.

It protects the last remaining habitat for these special species.
The city has a public marina, along with other private marinas and yacht clubs. There's a public fishing pier in town, and another one on the San Joaquin River near the Antioch Bridge.
Protecting the Burrowing Owl
In 2008, western burrowing owls moved into an area planned for new homes. These owls are a special concern in California. Their population has dropped a lot over the years.
Even though they are protected from harm, their homes can be removed outside of nesting season. In 2009, people protested to protect the owls. Local residents and an environmental group built new, artificial burrows for the owls. This was to help the displaced owls find new homes. Antioch was the first city in the East Bay to set aside land specifically for burrowing owls.
