Louisiana Parishes

Louisiana is divided into sixty-four parishes. On March 31, 1807, the territorial legislature divided the state into 19 parishes, without getting rid of the old counties (which continued to exist until 1845). In 1811, a constitutional convention organized the state into seven judicial districts, each consisting of groups of parishes. In 1816, the first official map of the state used the term, as did the 1845 constitution. Since then, the official term has been parishes.
