The electoral history of each district in the Ohio House of Representatives can be traced from 1966 to the present.
Originally,
The constitution ... contained a complicated formula for apportionment, the so-called "major fraction rule." Under it, the state's population was divided by 100, with the resulting quotient being the ratio of representation in the House of Representatives. Any county with a population equal to at least half the ratio was entitled to one representative; a county with a population of less than half the ratio was grouped with an adjacent county for districting; a county containing a population of at least one and three-fourths the ratio was entitled to two representatives; a county with a population equal to three times the ratio was entitled to three representatives. To determine Senate districts, a similar procedure was followed; the starting point, however, was figured by dividing the state's population by 35. The ratios for the House and Senate and the resulting apportionment was determined by a board consisting of the governor, auditor, and secretary of state.
In 1903, at the urging of U.S. Senator Mark Hanna, who led the state's politically dominant Republican political machine, Ohio voters amended the state constitution to award each county one representative. The remaining representatives were apportioned to the counties on the basis of population. This provision later became known as the "Hanna amendment".
In June 1964, the Supreme Court of the United States ruled in Reynolds v. Sims, 377 U.S. 533 (1964) that state legislature districts had to be roughly equal in population. A case challenging the "Hanna amendment" reached the Supreme Court at about the same time as Reynolds v. Sims. On June 22, 1964, the Supreme Court held Ohio's method for apportioning representatives (but not state senators) to be in violation of the Constitution per the decision in Reynolds v. Sims. On remand, the United States District Court for the Northern District of Ohio ordered the state legislature to adopt a new apportionment scheme to comply with the holding in Nolan v. Rhodes.
Elections under the new apportionment scheme were first held in November 1966, for terms to begin per the Ohio Constitution on the first day in January 1967.
