Martin Luther King made a major difference in the American history. He helped get the rights to African American in United States. He believed the rights of people to live free of domination by others is the most fundamental goal of democracy. The will of the majority becomes the law but that law must protect the rights of everyone, not just those of the majority. King also believed in civil disobedience, when acted for the correct reasons, was a useful tool to fight unjust law. King was a famous person then, now and will be.
King found a law to be unjust then civil disobedience would be correct and morally right. King's guidelines to determine if a law is just or unjust were an integral part of his views on civil disobedience. In defining the definition between just and unjust laws, King says that a just law is those laws that align with the moral law or the law of god. On the other hand, an unjust law is that law that is not aligned with no moral law. Any law that did not agree with the law of god was unjust. However, god's law has many different meanings, since King being a Baptist minister believed the definition of god's law to be any law that does not contradict or undermine the teachings in the Bible. If any law contradicts the Bible, then King would judge that law unjust.
Secondly, King took huge step to fight segregation. He ended the separation of blacks and whites. He believed that any law that uplifts human personality was just and any law that degrades human personality was unjust. As we read in in the essay "Letter from Birmingham Jail", there were separate bathrooms, schools, water fountains, and churches. The blacks didn't had rights to vote and pick a leader for their country. Segregation damages the soul of that one segregated against thus making it an unjust law. King quotes St. Augustine " an unjust law is no law at all". He then includes the law of God as his moral theory to provide the framework upon which to judge the law.
