• Florence Township was judicially independently organized in 1817. This township had been originally established about 1808 as "Jesup" Township, in honor of one of its original land-speculators; however, the township name was shortly later changed to "Florence" (due to that land-owner having fallen into disfavor with the pioneer-settlers who had purchased their farms from him).

The township is governed by a three-member board of trustees, who are elected in November of odd-numbered years to a four-year term beginning on the following January 1. Two are elected in the year after the presidential election and one is elected in the year before it. There is also an elected township fiscal officer, who serves a four-year term beginning on April 1 of the year after the election, which is held in November of the year before the presidential election. Vacancies in the fiscal officership or on the board of trustees are filled by the remaining trustees.
