Answer:
the Declaration of Independence
Step-by-step explanation:
Interestingly, King was not a communist, but definitely not an anti-communist either. The fact that he relied on the masses in the struggle with local and federal authorities for economic, political and social equality, that he sought to strengthen ties with democratically-minded white Americans and, above all, with the trade union movement, that he linked the struggle for the freedom of blacks with the struggle for the world that he readily studied with all supporters of progress, including the Communists, testifies to his political growth. This is evidenced by his speeches and published articles. He said that the US Declaration of Independence (1776) contains exciting phrases about universal brotherhood, which was never achieved due to slavery and subsequent segregation.
