Final answer:
The focus of desegregation is Integration, which aimed to end racial segregation and discrimination, supported by significant legislation like the Civil Rights Act of 1964, and overcome both de jure and de facto segregation.
Step-by-step explanation:
The focus of desegregation is Integration. Desegregation efforts were primarily aimed at ending racial segregation and discrimination, particularly in schools and other public facilities. This strive for equality was legally supported by landmark decisions and legislation, such as the Brown v. Board of Education ruling in 1954, which deemed 'separate but equal' unconstitutional in public education, and subsequent acts like the Civil Rights Act of 1964 and the Voting Rights Act of 1965. Desegregation not only sought the cessation of de jure (legal) segregation but also aimed to overcome de facto (practical) segregation that persisted even after laws changed. Integration was a vital component of the Civil Rights Movement that encountered significant opposition, often requiring federal intervention to achieve racial balance in various social institutions, including the military and public schools.
