1830-39 the Indians thrived in what was known as the "golden years".
Then the civil war started and the indians had to choose a side. Sadly they chose the wrong one.
Because they chose the wrong side their land was cut in half and their governments were abolished.
The positives were the slaves were given citizenship and property, railroads were built, no territorial gov, and a new treaty was made. The negatives were their loss of land, and prices in land for the seminoles.
The plains indians were removed from their homes in the plains and made to live on the half of Oklahoma that was taken from the 5 tribes. The plains indians had a meeting at medicine lodge creek which was the largest gathering of them on record.
In the summer of 1867 there was constant wars between the U.S army and plains tribes. The battle of Washita killed 102 indians and 800 horses. Pretty soon the government said no more treaties and took away all state rights they had given indian tribes. The tried to americanize indians and erase all signs of their culture.
