Creation of the Toledo Strip thumb|left|upright|Michigan Territory governor, Lewis Cass (1813–1831) The location of the border was contested throughout the early 19th century. Residents of the Port of Miami—which would later become Toledo—urged the Ohio government to resolve the border issue. The Ohio legislature, in turn, passed repeated resolutions and requests asking Congress to take up the matter. In 1812, Congress approved a request for an official survey of the line.. Delayed because of the War of 1812, it was only after Indiana's admission to the Union in 1816 that work on the survey commenced. At that time, the border between Michigan and Indiana was altered from the Northwest Ordinance boundary – over the protests of the Michigan Territory – moving it northward to give the new state substantial frontage on Lake Michigan.
