In spite of the fact that it had just been a piece of the United States for under two years, California turns into the 31st state in the association on this day in 1850.
Mexico had reluctantly surrendered California and a lot of its northern domain to the United States in the 1848 Treaty of Guadalupe Hidalgo. At the point when the Mexican representatives marked the settlement, they imagined California as a locale of sluggish mission towns with a little populace of around 7,300-not a staggering misfortune to the Mexican realm.

Their lament may have been substantially keener had they realized that gold had been found at Sutter's Mill in Coloma, California, nine days before they marked the peace arrangement.
 All of a sudden, the best dash for unheard-of wealth in history was on, and "forty-niners" started flooding into California pursuing the clenched hand measured gold pieces reputed to be strewn about the ground simply holding up to be grabbed. California's populace and riches soar.
Most recently gained districts of the U.S. experienced extensive stretches as domains before they had the 60,000 occupants expected to accomplish statehood, and preceding the Gold Rush, displacement to California had been slow to the point that it would have been a long time before the populace achieved that number.

Looked with such quick development, and also a prickly congressional discussion over the subject of servitude in the new regions, Congress enabled California to hop straight to full statehood while never going through the formal regional stage.
After a malevolent discussion between the slave-state and free-soil advocates, Congress at long last acknowledged California as a free-work state under the Compromise of 1850, starting the state's long rule as the greatest monetary and political power in the far West.
