Juan Crow is a type of law or policy related to enforcement of immigration statues against Latinos in the United States. The term is patterned after Jim Crow laws that enforced racial segregation and kept blacks as an underclass.
Certain laws in Arizona, Alabama, and Georgia have been considered Juan Crow laws.
California's Proposition 187 was considered a Juan Crow law. It required citizenship screening of residents and denied social services like health care and public education to illegal immigrants.
In the 1940s, California public schools were racially segregated. Mexican and Mexican American students attended separate "Mexican schools". This de jure segregation was deemed unconstitutional by the Mendez v. Westminster federal court case.
