The Birmingham Campaign spurred civil rights struggles in other states across the country and positioned Martin Luther King as a great black leader.

We can arrive at this answer because:

The Birmingham Campaign started in April 1963.

This campaign started the fight for civil rights, where blacks gathered in groups, to make protests, marches, and claims about their rights.

They also began to break segregation laws and began to occupy places that were not allowed for them, such as the first seats on a bus.

The campaign caused a lot of repercussion across the country and annoyed those responsible for racist and segregationist laws. By the end of that campaign, the struggle for civil rights was established across the country, and in addition, Martin Luther King had positioned himself as a great leader and an inspiration to many people.
