Explanation:

The horse was introduced to the American continent with the arrival of the European conquerors in 1492. The European military used these animals as a means of transport, a work tool and even for military purposes.

Once introduced to the continent, this animal gave Europeans a considerable advantage in battle, as it provided faster mobility and a higher position from which to fight; its use was one of the strategic keys of the victory of the conquerors over the natives.

This animal, once introduced in the continent, began to reproduce and form increasingly numerous groups. Both Europeans and natives used it; In the case of the latter, who lived a life more in contact with nature, hunted and worked the land, the horse became an indispensable tool for day to day activities. Thus, as an indirect consequence of its introduction by Europeans, the horse became a fundamental element of the lives of Native Americans.
