23 May - South Carolina is admitted as the 8th U.S. state.

South Carolina was admitted as the eighth state of the United States on 23 May 1788, following its ratification of the U.S. Constitution. This ratification allowed South Carolina to join the Union under the framework of the new federal government established by the Constitution.

This ratification marked its official entry into the Union under the newly established federal government outlined by the Constitution. Prior to this, South Carolina was one of the original thirteen colonies that declared independence from Great Britain in 1776 and subsequently became one of the thirteen original states of the United States under the Articles of Confederation.
