Violence and discrimination against
Mexican Americans (usually against those of lower class and of visible Amerindian ancestry) continued into the 1950s and 1960s. Many organizations, businesses, and homeowners associations had official policies to exclude Mexican Americans. In many areas across the
Southwest, Mexican Americans lived in separate residential areas, due to laws and real estate company policies. This group of laws and policies, known as
redlining, lasted until the 1950s, and fall under the concept of official segregation. In many other instances, it was more of a general social understanding that Mexicans should be excluded from
White society. For instance, signs with the phrase "No Dogs or Mexicans" were posted in small businesses and public pools throughout the Southwest well into the 60's. Some members of the Mexican American community began to question whether assimilation was possible or even desirable. At the same time, a sense of ethnic consciousness and unity was forming, especially among the youth, around the
plight of the farmworkers. Mexican Americans, some of whom began calling themselves "
Chicanos" as a symbol of ethnic pride, also began to uncover their history and critically analyze what they learned in public schools. With this new sense of identity and history, the early proponents of the Chicano movement began viewing themselves as a colonized people entitled to
self-determination of their own. Some of them also embraced a form of nationalism that was based on their perception of the failure of the United States government to live up to the promises that it had made in the
Treaty of Guadalupe Hidalgo. ==Functions and basis==
