Illinois was the first state to ratify the amendment prohibiting slavery.

On January 31, 1865, Illinois Governor Richard J. Oglesby got word that the U.S. House of Representatives had finally given its blessing to the controversial 13th Amendment, clearing the way for it to be sent to the states for ratification.

The very next morning, Gov. Oglesby paid the legislature a visit and impressed on them the importance of immediate ratification. Three and a half hours later, both chambers had approved it. After the Land of Lincoln led the way, 26 other states followed. On December 18 of the same year, the abolition of slavery officially became the law of the land.
