Answer-The goal of the Americanization movement that gained popularity between 1875 and 1910 was to encourage immigrants to assimilate into American culture. The movement believed that immigrants should adopt American customs, language, and values in order to become more fully integrated into American society. The Americanization movement was motivated by a desire to promote national unity and to reduce the influence of foreign cultures in the United States. The movement established classes, programs, and institutions that aimed to teach immigrants about American history, government, and culture.
