Answer:
The Iroquois and Algonquin lived in the Northeast US and southeast Canada. The Anasazi lived in the Southwest US. The Iroquois and Anasazi lived a more sedentary lifestyle, while the Algonquin lived a more nomadic lifestyle. The Algonquin hunted and fished for food, while the Iroquois and Anasazi hunted, but also grew crops. Algonquin lived in wigwams (dome-shaped homes), Iroquois lived in long houses, and the Anasazi lived in Adobe style homes called pueblos. They all used what was available in nature for the creation of their homes. Algonquin society was patriarchal, Iroquois was matriarchal, and Anasazi was more matriarchal. The Algonquin and Iroquois were actually confederacies. They were actually different tribes of native americans that banded together in times of need.
No one is sure how the Anaszi declined. Some believe that they were attacked by a more hostile group or groups of indians. Others believe that they exhausted the few natural resources that existed within their desert environment. The Algonquin and Iroquois societies still exist and thrive today. They are prominent in their ancestral lands and have played key roles within both US and Canadian governments to protect their land and interests.
The Walla Walla Council was held in 1885, in Waiilatpu, in the Walla Walla Valley in the state of Oregon.
That treaty defined the lives of tribes like Umatilla, Cayuse, and Walla Walla when the U.S. government invited the tribes to the council in order to protect the interest of their tribes.
The tribes attended to protect their sacred lands and did not want to surrender their culture neither their freedom.
Before the council was held, government employees destroyed Indian economies, divided the territories, and offered their sacred lands outsiders.
I assume you mean WWI as there were only two. In WWI Americans participated. Many of the able men went to war. While the women, children, and disabled stayed and helped with the war effort. Most of the effort back home was from the women.
It emphasized US economic strength. It emphasized US military strength. It promoted the strength of US scientists and inventors.
