What are two types of protests that Martin Luther King Jr. organized across the country?

1. Montgomery bus boycott, 1955-56

Lasting just over a year, the Montgomery bus boycott was a protest campaign against racial segregation on the public transit system in Montgomery, Ala. The protest began, on Dec. 1, 1955, after African-American Rosa Parks was arrested for refusing to give up her seat on a bus to a white person. The next day, Dr. King proposed a citywide boycott of public transportation at a church meeting.

2. 'Poor people’s campaign,' 1968

Organized by Dr. King and the Southern Christian Leadership Conference in 1968, the so-called "poor people’s campaign" sought to address issues of economic justice and housing for the poor. King traveled the country to assemble a diverse group of protesters representing the poor who would march on Washington until Congress created a bill of rights for poor Americans.
