Introduction to Sacramento: Sacramento (Sacramento, also translated as Sacramento) was originally a castle built by Swiss immigrants. In January 1848, James W. Marshall accidentally discovered it in the local river while building a sawmill. After the news came out, gold diggers from all over the world poured into California in large numbers, setting off a famous gold rush in history. Sacramento also quickly transformed from a small town into an important economic and transportation hub. Driven by the gold rush, Sacramento's commercial and agricultural development was astonishing. Trains, horse-drawn carriages, and ships were constantly coming and going. All kinds of goods and people were coming in and out. It was a busy scene. The city of Sacramento was also established and became California. The earliest autonomous city. In 1854, the California Legislature and state government moved to Sacramento and became the capital of California.
