The Evangelical Church in Wurttemberg, known in German as the Evangelische Landeskirche in Wurttemberg, traces its founding to 1534, when Duke Ulrich of Wurttemberg imposed the Reformation on his duchy. The reformer Johannes Brenz began organizing its parishes on Lutheran lines, and the first public evangelical service was held in the Stuttgart Stiftskirche on 16 May 1534, the date the Landeskirche marks as its own beginning.
The church is one of twenty regional Lutheran and Reformed member churches making up the Evangelical Church in Germany (EKD), covering most of the historic region of Wurttemberg in southwestern Germany with its seat in Stuttgart. As a body under German public law, it is funded partly through church tax (Kirchensteuer), a financing model shared across the EKD's twenty regional churches, and it presents its own annual financial statement each year to its regional synod rather than relying solely on the EKD-wide aggregate figures reported for the federation as a whole.
Nearly five centuries after Brenz organized its first parishes on Lutheran lines, the Landeskirche continues to operate as a full regional church, with its own synod, clergy and parish structure serving the historic Wurttemberg region within the wider EKD federation, a continuity running from a single duke's decision in 1534 to a functioning regional institution today.
