John II, Duke of Saxe-Weimar (Johann Maria Wilhelm) (Weimar, 22 May 1570 – Weimar, 18 July 1605), was a Duke of Saxe-Weimar and Jena.

Biography

He was the second son of John William, Duke of Saxe-Weimar and Dorothea Susanne of Simmern.

His father died in 1573, when John was only three years old. Since at the time his older brother Frederick William I was also under age, the duchy of Saxe-Weimar (originally awarded to John) was governed by a regency. In 1586 his older brother reached adulthood and took full control of the duchy, including Weimar. However, he died in 1602 and the full duchy was inherited by John, because his nephews (the sons of his deceased brother) were under age.

John was more interested in natural sciences and art than politics, and therefore only against his will took over the regency of the duchy on behalf of his nephews. But when they demanded their own inheritance in 1603, he resisted their demands. Finally, John and his nephews made a treaty dividing the duchy: Altenburg was taken by the sons of Frederick William I, and Weimar-Jena was retained by John.

This line of Saxe-Altenburg became extinct in 1672, and all the inheritance passed to the line of Saxe-Weimar, John's descendants.
