Martin Luther King's famous speech "I Have a Dream" deals with racism and segregation of people of color. He says in his speech that he wishes for a world where those things don't exist, and where every human is free and shares equal rights as everyone else, regardless of religion, gender, skin color, or sexual preferences. Hope this helps!

If you are talking about the development of political parties, then the issue that led it to them was “the struggle over ratification of the federal Constitution of 1787” (loc.gov).
Federalists, such as Alexander Hamilton, wanted a strong, central government and the Anti-Federalists, like Thomas Jefferson, “advocated states’ rights instead of centralized power”. (Library of Congress)
