how did civil disobedience marches and big events affect the law support of civil rights? short answer

The civil disobedience marches and big events initiated social change in the civil rights of the people.

Explanation:

The height of the civil right's movement occurred in the 1950s and 1960s. This struggle continued as the African-Americans fought for justice in the racial system. Several movements consisting of civil disobedience and big events (marches and boycotts) occurred. Examples of these are: Albany Movement, March on Washington, Chicago Freedom Movement, Vietnam War Opposition and so on.

With so many campaigns happening, the government tried responding to them (in the end) by ending hunger, providing equality such as the Birmingham Campaign which resulted into the access of all races in Alabama City. The movements also boosted the support for social change.
