Just noticed that the map actually runs from 1784 to the present.
One thing to watch is how much reservation land is lost between 1887 and now. Almost all of OK and MT are lost in one deal. The Dawes Act of 1887 only applied to the Five Civilized Tribes: Cherokee, Choctaw, Muskogee, Chickasaw, and Seminole. Those were the peoples whose land was occupied by that act. (They were told to join up with the U.S. and get citizenship. It was actually a way to break up tribes and get their landholdings.)
I agree that it would be good to see the two other states. Their history is different, but comparable to the contiguous U.S.
California has a unique history because it is coastal and the interior is largely desert or mountains. The state was first explored by the Spanish in 1535. The U.S. (as an independent entity) didn’t have an early impact here, but the Spanish, Portuguese, English, and Mexico all did. In 1545, a typhus epidemic brought by Europeans killed hundreds of thousands of Californian natives. It wasn’t until 1846 that the U.S. invaded Mexico in the Mexican War, and California was part of the treaty that ended the war. From that point on, anything done to California natives can blamed on the U.S.
