The California gold rush (1848–1855) was a gold rush that began on January 24, 1848, when gold was found by James W. Marshall at Sutter's Mill in Coloma, California.

The sudden influx of gold into the money supply reinvigorated the American economy; the sudden population increase allowed California to go rapidly to statehood in the Compromise of 1850. The gold rush had severe effects on Native Californians and accelerated the Native American population's decline from disease, starvation, and the California genocide.

The 2020 United States presidential election in California was held on Tuesday, November 3, 2020, as part of the 2020 United States presidential election in which all 50 states plus the District of Columbia participated. California voters chose electors to represent them in the Electoral College via a popular vote, pitting the Republican Party's nominee, incumbent President Donald Trump, and running mate Vice President Mike Pence against Democratic Party nominee, former Vice President Joe Biden, and his running mate Kamala Harris, the junior senator from California. In the 2020 election, California had 55 electoral votes in the Electoral College, the most of any state. Biden won by a wide margin, as was expected; however, California was one of six states where Trump received a larger percentage of the two-party vote than he did in 2016. This election also marked the first time since 2004 that the Republican candidate won more than one million votes in Los Angeles County due to increased turnout.
