Sacramento was founded in 1848 as Sutter’s Fort. It was incorporated as a city in 1850. It was one of California’s first incorporated cities. Perhaps no other city was as important to the gold and land rushes of the 1850’s as Sacramento. The city’s population swelled after gold was found 50 miles to the north. In 1855, it was declared capital of California. Sacramento soon became a very important city, and was made the western terminus of both the Pony Express (an overland mail route from St. Charles, Missouri to Sacramento) and first Transcontinental Railroad (a cross-country railroad).
