Historical Evolution
The origins of the diocese date back to 1803, when Prince Primate Karl Theodor von Dalberg appointed a Vicar General for the "New" State of Württemberg. This role was filled by Franz Karl Joseph Fürst von Hohenlohe-Waldenburg-Schillingsfürst, an auxiliary bishop who consecrated the current Co-Cathedral in Stuttgart. While the first seat of the vicariate was located at Ellwangen Abbey, it transitioned to Rottenburg in 1817.
The formal establishment of the Diocese of Rottenburg occurred on August 16, 1821, via the papal bull De salute animarum. This new entity was created from territory previously belonging to the suppressed Diocese of Konstanz. The diocesan structure was finalized on May 20, 1828, with the enthronement of its first bishop, Johann Baptist von Keller.
To better reflect its administrative and population centers, the diocese was renamed the Diocese of Rottenburg-Stuttgart on January 18, 1978.
Major Churches and Landmarks
The diocese is anchored by two primary seats: the episcopal see at St. Martin's Cathedral in Rottenburg and the St. Eberhard Co-Cathedral in Stuttgart.

Beyond these seats, the diocese oversees three minor basilicas, which are churches granted special privileges by the Pope:
- Basilika St. Vitus in Ellwangen (the former Cathedral of Ellwangen Abbey).
- Basilika St. Martin at the Benedictine Wiblingen Abbey in Ulm.
- Basilika St. Martin von Tours und St. Oswald in Weingarten, Württemberg.
Additionally, the diocese is associated with the former Cistercian monastery Kloster Maulbronn in Maulbronn, a World Heritage Site that served as a Catholic institution before becoming a Lutheran seminary and school.
Governance and Leadership
The diocese is currently led by Bishop Klaus Krämer. He is supported by several auxiliary bishops—bishops assigned to assist the diocesan bishop—including Thomas Maria Renz, Gerhard Schneider, and Matthäus Karrer. The administrative operations are managed by Vicar General Clemens Stroppel.

The lineage of episcopal ordinaries includes notable figures such as Cardinal Walter Kasper, who served as bishop from 1989 to 1999 before taking on prominent roles within the Vatican, including the President of the Pontifical Council for Promoting Christian Unity.
