What was the League of Nations? Who was a part of it?

LON was the first worldwide intergovernmental organisation whose principal mission was to maintain world peace. (Googled)

The founder of LON was Woodrow Wilson.

It was founded in January 10, 1920 but ceased in April 20, 1946.

"The Council was a coalition of the four permanent members: France, Italy, Japan, and the United Kingdom. Germany joined in 1926, but left in 1935. In September 1934, the Soviet Union entered the League of Nations.

Member: Peru; Colombia; Turkey; Soviet Union" (Googled)

Good luck! Hope this helped! :) I added some additional things too.

after the spaniards introduced horses to plains native americans, the lives of the tribes changed. tribes became less settled and sedentary. the horse allowed them to hunt animals such as bison or buffalo, and, instead of staying in one place, tribes began to be nomadic.
