When did george Wallace block black students from registering for school in Alabama?

George Wallace, the Governor of Alabama, famously blocked black students from registering at the University of Alabama on June 11, 1963. This event was part of his staunch opposition to desegregation and civil rights for African Americans. Wallace's actions were seen as a direct challenge to federal authority and civil rights legislation at the time. The standoff ended when federal intervention, including the presence of U.S. Marshals, allowed the students to enroll.
