In honor of her Birthday, today is officially Rosa Parks day. On December 1st, 1955 the world would come to know Rosa Parks. On this day when asked (because of her race), choose not to give up her seat on an Alabama bus. Rosa Parks actions started a non-violent protest in Montgomery Alabama, that eventually led to a Supreme Court decision, changing Segregation Laws forever.
Not long after Parks actions, a district court ruled against Segregation Laws and ordered the state of Alabama to desegregate its buses. The case was appealed by the City of Montgomery Alabama and brought to the US Supreme Court, where the Justices ruled in favor of the District Court ruling to desegregate its buses.
Parks actions which helped start the protest led to a judgement being handed down from the highest court, essentially reaffirming what she did that fateful day. The Supreme Court ruled conditions under segregation deprived people of equal protections under the 14th Amendment.
Many say Parks actions that day helped start the Civil Rights Movement which eventually led to the 1964 Civil Rights Act.
One seemingly small act by one individual led to great change for all.
