Duchy of Saxe-Eisenberg

1680 CE – 1707 CE · capital Eisenberg

Tiny Ernestine duchy in eastern Thuringia whose single duke built a celebrated baroque palace chapel.

Origins

In the 1680 division of the inheritance of Ernest the Pious, his fifth son Christian received Eisenberg and its district, between Gera and Jena, founding the Duchy of Saxe-Eisenberg.

Rule and society

Christian rebuilt Christiansburg Palace in Eisenberg and added a richly decorated baroque chapel, still one of the finest in Thuringia. He was interested in alchemy and kept a small Lutheran court. The duchy was largely rural, with no independent policy of note.

Decline and legacy

Christian died in 1707 without a male heir. After a dispute among his relatives, Saxe-Eisenberg passed to Saxe-Gotha-Altenburg; in 1826 it went with Altenburg to the new Duchy of Saxe-Altenburg.
