Final answer:
Influences from earlier American documents, such as the Declaration of Independence and the Emancipation Proclamation, made Dr. Martin Luther King Jr.'s message in favor of civil rights more effective.
Step-by-step explanation:
Influences from earlier documents in American history made Dr. Martin Luther King Jr.'s message in favor of civil rights more effective. One such influence was the Declaration of Independence, which stated that all men are created equal and have the right to life, liberty, and the pursuit of happiness. This reinforced King's argument that segregation and discrimination were unjust and went against the principles of the founding documents. Another influential document was the Emancipation Proclamation, which abolished slavery. King drew on the ideals of freedom and equality established by this document to advocate for equal rights for African Americans. Additionally, the Constitution and its amendments, particularly the Fourteenth Amendment, played a significant role in shaping King's message. The Fourteenth Amendment guarantees equal protection under the law and due process, principles that King emphasized in his fight for civil rights.
