California, USA (06)

I already have Californian maps (you've seen them) but this one is different....funny how some places have NO maps like this, while others have several different ones.

The area known as Alta California was colonized by the Spanish Empire beginning in the late 18th century. It and the rest of Mexico became an independent republic in 1821. In 1846 California broke away from Mexico, and after the Mexican-American war Mexico ceded California to the United States. California became the 31st state admitted to the United States on September 9, 1850.
This feels like the US have been collecting states one by one, growing in total area and eventually becoming what they are today...
