Duchy of Saxe-Jena

1672 CE – 1690 CE · capital Jena

Brief Ernestine duchy centred on the university town of Jena, carved out for a younger Weimar prince and gone within two decades.

Origins

Duke William of Saxe-Weimar died in 1662 and his lands were divided among his sons. In 1672, after a further rearrangement following the extinction of Saxe-Altenburg, Bernhard received Jena and its surroundings as the Duchy of Saxe-Jena.

Rule and society

Bernhard ruled from Jena, rebuilding the castle there and maintaining a modest Lutheran court. The University of Jena, founded in 1558, was shared among the Ernestine dukes and remained the town's main institution. The duchy was too small to pursue an independent policy and relied on its larger Ernestine relatives.

Decline and legacy

Bernhard died in 1678 and his only son John William died as a child in 1690. The duchy was then divided between the Duchy of Saxe-Eisenach and Saxe-Weimar, with Jena itself eventually going to Weimar.
