Historically, Latinos have struggled against discrimination in North America in various ways such as forming political organizations that represented their particular group interests. The early organizations developed along single group lines or "national origin" groups. For example, Chicanos formed political organizations for Chicanos, Puerto Ricans formed organizations for Puerto Ricans, and so forth. It was not until after the 1960s social movements and new ethnic radicalism that Latino groups attempted to form coalitions that contained a variety of Latino groups or "pan-Latino" coalitions. These coalitions began to represent Latinos on a national level and started to have some impact on the national political arena. In the process the phenomenon also added to the meaning of coalitions.
