Why Ohio celebrates statehood on March 1, and what happened in 1953
Congress admitted Ohio in February 1803, but the date Ohio observes is March 1 — and it was only fixed there by a resolution 150 years later.
Ohio marks Statehood Day on March 1. The legislation that made Ohio a state is dated earlier, and the gap between the two has a documented explanation.
The sequence began with the Northwest Ordinance of 1787, which set out how the territory north-west of the Ohio River would be administered and eventually divided into states. In 1802 Congress passed what is known as the Enabling Act — formally “An act to enable the People of the Eastern division of the territory Northwest of the river Ohio to form a Constitution and State Government”, dated April 30, 1802. It invited Ohioans to hold a constitutional convention.
That convention met at Chillicothe in November 1802 and adopted Ohio’s first constitution on November 29, 1802. On February 19, 1803, Congress passed an act recording that the citizens of Ohio had adopted a constitution in accordance with the Enabling Act and that the state “had become one of the United States of America”.
So the legal act of admission is dated February 19, 1803. March 1, 1803 is a different event: it is the day the first Ohio General Assembly met, at Chillicothe, after elections held that January. For much of Ohio’s history the two dates competed.
The matter was settled retrospectively. The National Archives records that March 1, 1803 “was retroactively made the statehood date by a 1953 Resolution of the United States Congress”. The United States Senate’s own Ohio timeline states that “In 1953, Congress established the date of Ohio statehood as March 1, 1803 — the date that Ohio’s state legislature met for the first time.”
Ohio was the seventeenth state admitted to the Union, and that number is built into the state’s symbols: the flag carries seventeen stars, and the folding procedure written into Ohio law produces seventeen folds.
Chillicothe, where both the convention and the first General Assembly met, was Ohio’s first capital. Columbus became the seat of state government later.
