The 13th Amendment to the Constitution of the United States was ratified on this date in 1865. It reads, Neither slavery nor involuntary servitude shall exist in the United States.
In February 1788, a compromise was reached under which Massachusetts and other states would agree to ratify the document with the assurance that amendments would be immediately proposed. The Constitution was thus narrowly ratified in Massachusetts, followed by Maryland and South Carolina. On June 21, 1788, New Hampshire became the ninth state to ratify the document, and it was subsequently agreed that government under the U.S. Constitution would begin on March 4, 1789. In June, Virginia ratified the Constitution, followed by New York in July. On September 25, 1789, the first Congress of the United States adopted 12 amendments to the U.S. Constitutionâthe Bill of Rightsâand sent them to the states for ratification.
