apache indians gave? im doing a project on the apache indians and i cant find any of the contributions from them

The Apachean tribes were historically very powerful, constantly at enmity with the whites for centuries. The U.S. Army, in their various confrontations, found them to be fierce warriors and skillful strategists.When the United States went to war against Mexico, many Apache bands promised U.S. soldiers safe passage through their lands. When the U.S. claimed former territories of Mexico in 1846, Mangas Coloradas signed a peace treaty, respecting them as conquerors of the Mexican's land. An uneasy peace (a centuries old tradition) between the Apache and the now citizens of the United States held until the 1850s, when an influx of gold miners into the Santa Rita Mountains led to conflict. This period is sometimes called the Apache Wars.
