Saxe-Coburg (German: Sachsen-Coburg) was a country in today's Bavaria, Germany. It was part of the Duchy of Saxe-Coburg-Eisenach after the Division of Erfurt in 1572. In 1596 Saxe-Coburg-Eisenach was split, Johann Casimir got Saxe-Coburg and Johann Ernst got Saxe-Eisenach. When Casimir died in 1633, his brother Ernst of Saxe-Eisenach both countries until he died in 1638. Saxe-Coburg was then given to other Ernestine duchies.
It became again a duchy in 1681. From 1699, when Albrecht of Saxe-Coburg died without sons until 1735 it shared a ruler with the Duke of Saxe-Saalfeld. In 1735 the two duchies were merged as Saxe-Coburg-Saalfeld.
