Today’s Louisiana counties did not always exist in the present form. They went through many different changes in the space of a few short years. Louisiana Parishes were first formed while part of the Orleans Territory.

Louisiana Territorial Parishes

The Territory of Orleans or Orleans Territory was created on October 1, 1804, until the State of Louisiana entered the union as the 18th state on April 30, 1812 with 25 parishes.

1805 Louisiana Counties

Following the Louisiana Purchase in 1803, the territorial legislature organized 12 Louisiana counties. Those (Orleans County, LaFourche County, German Coast, Acadia County, Iberville County, Attakapas County, Pointe Coupée County, Opelousas County, Rapides County, Concordia County, Natchitoches County, and Ouachita County.) on April 10, 1805.

The borders of these counties were poorly defined, but they roughly coincided with the colonial parishes, and hence used the same names.

The parish or parishes referred to the Act of April 10, 1805 were existing ecclesiastical jurisdictions (established under previous Spanish rule) rather than precisely defined civil divisions.

The ecclesiastical districts had never been precisely bounded, nor did such parishes exist throughout the new territory. As a result, county boundary lines can only be estimated.

After creation of civil parish system in 1807, the early county divisions were generally used for certain electoral and taxation purposes.

1807 Louisiana Parishes

The 19 Louisiana parishes established on April 14, 1807 were civil divisions which reused the earlier ecclesiastical boundaries and names. The division into civil parishes did not abolish the original 12 counties established on April 10, 1805.

This and subsequent laws set up a dual system in which the counties existed “for the purpose of making the election of the representatives of the territory, and levying the territorial taxes”, while the parishes took over jurisdiction of all civil, criminal, probate and other judicial matters.

The 19 original Louisiana parishes were joined by Catahoula Parish in 1808, and in 1810 four additional parishes were created from the formerly Spanish West Florida territory.

In 1811, Louisiana was organized into 7 judicial districts, each consisting of groups of parishes. In 1816, the first official map of the state used the term parish, as did the 1845 constitution.

1845 Louisiana Constitution

In 1843 the county was abolished as an electoral unit. The dual county / parish system remained in effect until the state constitution of 1845.

Though there was no legislative act formally abolishing the old counties, but when the state constitution was rewritten in 1845 all remainders of the county system were eliminated.

Since then, the official term for Louisiana’s primary civil divisions has been parishes.

Louisiana Parishes Today

Today, Louisiana is divided into 64 counties.  States bordering Louisiana are ArkansasMississippi and Texas.

Today, 38 Louisiana parishes are governed by a council called the Police Jury. The remaining 26 parishes have various other forms of government, including: council-president, council-manager, parish commission, and consolidated parish/city
