There are several intriguing events that took place on February 22 in California's history. Here are five interesting facts that highlight some of these events:

1. On February 22, 1856, the California State Assembly approved a bill that would provide funding for the construction of the first asylum for the insane in California. The asylum was later built in Stockton and opened in 1853.

2. February 22, 1878, marked the first day of construction of the Southern Pacific Railroad in Bakersfield. This railroad connected San Francisco to Southern California and became an important transportation link for commerce and industry in the state.

3. On February 22, 1915, the California State Legislature passed a bill allowing women to serve on juries in the state. This made California the first state in the Union to grant this right to women.

4. In 1974, on February 22, the California State Assembly passed a bill that decriminalized marijuana possession for personal use by adults. This law was later overturned by a federal judge but served as a precursor to the eventual legalization of marijuana in California in 2016.

5. On February 22, 2016, the Apple vs. FBI case made headlines when a federal magistrate ordered Apple to assist in decrypting an iPhone belonging to one of the San Bernardino shooters. The case sparked a heated debate on privacy, technology, and law enforcement, and ultimately, the FBI was able to unlock the phone without Apple's help.

In conclusion, February 22 marks several significant events in California's history, from the building of the first asylum for the insane and the construction of the Southern Pacific Railroad to the passing of legislation granting women the right to serve on juries and the decriminalization of marijuana possession for personal use.
