The Montgomery Bus Boycotts began as a response to the arrest of Rosa Parks.

Explanation:

Rosa Parks was an American civil rights activist, arrested for failing to adhere to the rules that dictate that blacks must surrender their seats in public transport for the Whites. She refused to give up her bus seat to a white man in Montgomery. She was eventually arrested for the 'violation' of the federal law/rule.

Her arrest sparked a lot of protests in the nation, especially Alabama, where there has been 'silent' anger in the blacks and their need to get their voices heard. The racial discrimination that they had to endure at the hands of the white majority was one thing that greatly led and contributed to the unrest in the community. And the arrest of Rosa Parks was the 'igniting spark' that brought forth the outburst of all those suppressed feelings. Her arrest was met with the Montgomery Bus Boycott.
