Roman Catholic Diocese of Leavenworth explained

The Diocese of Leavenworth (Latin: Dioecesis Leavenworthensis) was a Latin Church former diocese and present titular see originally in and around Kansas, in the midwestern United States.

On 1857.01.06, it lost territory to establish the then Apostolic Vicariate of Nebraska, and the remainder was renamed as Apostolic Vicariate of Kansas.
On 22 May 1877, it was promoted as Diocese of Leavenworth, ceasing to be missionary and exempt.
On 2 August 1887, it lost territories to establish the Dioceses of Wichita and the Concordia.
On 29 May 1891, it was renamed as Diocese of Kansas City, Kansas / Civitatis Kansas (Latin).
On 5 March 1897, it was finally renamed as Diocese of Leavenworth.
