Cities and villages in Ohio, which all sprang from townships, are an extra layer of local government which exist above townships. Once the territory of a township is completely enveloped by cities and villages, the township government ceases to function under ORC 703.22. Often an entire township has been incorporated under a different name, such as Van Buren Township in Montgomery County, which became the City of Kettering in 1955. Another example is Mill Creek Township in south-central Hamilton County, which was absorbed by the City of Cincinnati in the 19th century.
