it attacked Seminole villages

Explanation:

Throughout 1836 Seminoles attacked plantations, outposts, and supply lines, and they stymied several efforts by the United States to subdue them. Near the end of the year, however, General Thomas Jesup took charge of the U.S.

its main object was the establishment of "settlement houses" in poor urban areas, in which volunteer middle-class "settlement workers" would live, hoping to share knowledge and culture with, and alleviate the poverty of, their low-income neighbors.
