Saxe-Coburg and Saxe-Eisenach: A History of Division and Union
The political landscape of early modern Germany was often defined by the fragmentation of territories among ruling families. One of the most notable examples is the history of the duchies of Saxe-Coburg and Saxe-Eisenach, whose existence was marked by a cycle of separation, brief reunification, and eventual absorption into larger states.
The Division of Erfurt
The origin of these duchies dates back to the Division of Erfurt in 1572. This event was the practical implementation of a decision made by the Diet of Speyer (a formal deliberative assembly of the Holy Roman Empire) in 1570. The goal was to separate the territories of Coburg and Eisenach from the Duchy of Saxe-Weimar.
These lands were granted to John Casimir and John Ernest, the two sons of John Frederick II. However, because both princes were minors at the time of the grant, the territories were initially governed by Elector August of Saxony, who served as their regent.

The period of guardianship ended in 1586, allowing John Casimir and John Ernest to begin ruling the duchy jointly. This partnership was short-lived; John Ernest soon withdrew from active governance to reside at his hunting lodge in Marksuhl.
By 1590, John Ernest formally renounced his participation in the government for a period of five years. Once this term expired, the two brothers reached an agreement to formally split the country. John Casimir took control of Saxe-Coburg, while John Ernest received Saxe-Eisenach.
The End of the Line and Redistribution
The stability of these separate duchies was disrupted by the lack of heirs. In 1633, John Casimir died childless, leading John Ernest to inherit his brother's possessions. This briefly reunited Coburg and Eisenach under a single ruler.
However, this union was temporary. When John Ernest also died childless in 1638, the line of the Dukes of Saxe-Coburg-Eisenach came to an end. The territory was subsequently divided between the other two existing Ernestine duchies (branches of the House of Wettin)—Saxe-Weimar and Saxe-Altenburg.

Following the events of 1638, Saxe-Coburg and Saxe-Eisenach remained separate entities. They would not belong to a common state again for nearly three centuries, until 1920, when all the Ernestine duchies merged to form the modern state of Thuringia.
