Columbus (1953). In 1953, during festivities celebrating Ohio's sesquicentennial, Ohio's congressional delegation asked the National Archives for the formal resolution declaring Ohio's admission to the Union. When no resolution was found; it was discovered that such a resolution had never been adopted. Congress quickly passed a resolution that declared admission of Ohio and postdated it to 1803.
Further Reading: Ohio has been a state in the Union since 1803, but because Congress had not established a method of granting statehood by resolution until 1812, when Louisiana was admitted as a state, confusion arose. Some in the United States declared that the 14th and 16th amendments to the United States Constitution were invalid. Admission of Ohio into the Union, by Benjamin H. Pershing, available in Volume 63 of Ohio History
