Rosa Parks proved to the world how strong African Americans can be. She influenced many other African Americans to stand up for what they believe in.

congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the government for a redress of grievances.
