Joachim Ernst was the son of the elector John George of Brandenburg and his third wife, Elisabeth of Anhalt-Zerbst. He travelled in England and Scotland in 1599.[1]

He took over in 1603, the government of the Margraviate of Brandenburg-Ansbach, after the old line of Franconian Hohenzollerns died out with the death of George Fredrick the Elder of the Ansbach-Jägerndorf branch. Joachim Ernst founded the younger branch of Ansbach line of the Franconian Hohenzollerns.

Succession rulesEdit

Charter of association of the Protestant Union in Auhausen on 14 May 1608 (now in the Bavarian State Archives): the signature of Margrave Joachim Ernst of Brandenburg is in the center

His predecessor, George Frederick had settled the succession of his two Franconian possessions (Brandenburg-Ansbach and Brandenburg-Kulmbach) in the House Treaty of Gera of 1598. In accordance with the provisions of this treaty, Margrave Joachim Ernst ruled Brandenburg-Ansbach and his brother Christian ruled neighboring Brandenburg-Kulmbach (Christian later moved his capital to Bayreuth, thereby changing its name to Brandenburg-Bayreuth).

Protestant UnionEdit

In the religious conflicts of the early 17th Century, Joachim Ernst tended to be in the Protestant-Calvinist camp and he also supported the Dutch struggle for independence. He took an active part in bringing about the Protestant Alliance of the Protestant Union, which was founded in 1608 on his territory, in the secularized monastery at Auhausen, near Nördlingen. The Union was, however, dissolved again in 1621, after the outbreak of the Thirty Years' War, in view of the military superiority of the imperial camp. After the dissolution of the Union, Joachim Ernst was held responsible for the outbreak of war by his Catholic opponents and he then completely distanced himself from his former allies.

Marriage and issueEdit

In 1612, he married Sophie of Solms-Laubach (1594–1651). They had five children:
