Both the congress of racial equality and the student nonviolent coordinating committee

They both organized Freedom Rides in the South.

The Freedom Rides, which began in 1961,  were carried out by activists who rode buses to protest how the Supreme Court's decision wasn't being enforced, in regard to segregated busing policies.  (The Court had ruled that segregation in transportation was unconstitutional.)

A few years later, in the summer of 1964, the Congress of Racial Equality (CORE), in cooperation with the Student Nonviolent Coordinating Committee (SNCC) and the National Association for the Advancement of Colored People (NAACP), also launched a campaign called "Freedom Summer."  The aim of the 1964 campaign was to get African Americans registered to vote.  The efforts focused especially on the state of Mississippi, where up until that point less than 10% of African American citizens were registered as voters.

a countries leader should be motivated by the common good of the country.
