California applied for statehood by drafting a state constitution, electing officials, and submitting its application to Congress in 1849, paving the way for its admission as the 31st state on September 9, 1850, under the Compromise of 1850.
What steps did Californians take to apply for statehood?
Californians first drafted and ratified a state constitution in 1849, then elected a governor and state legislators under its provisions.
Once the constitution was ready, the newly elected officials sent it straight to Congress. After some back-and-forth, Congress approved California’s admission. The state officially joined the Union on September 9, 1850, becoming the 31st state.
