The official date when Ohio became a state was not set until 1953, when the 83rd U.S. Congress passed legislation retrospectively designating the date of the first meeting of the Ohio state legislature, March 1, 1803, as that date. However, on April 30, 1802, the 7th U.S. Congress had passed an act "authorizing the inhabitants of Ohio to form a Constitution and state government, and admission of Ohio into the Union." (Sess. 1, ch. 40, 2 Stat.173) On February 19, 1803, the same Congress passed an act "providing for the execution of the laws of the United States in the State of Ohio." (Sess. 2, ch. 7, 2 Stat.201) The Biographical Directory of the United States Congress states that Ohio was admitted to the Union on November 29, 1802, and counts its seats as vacant from that date.
