On Joachim Ernst"s death Albert"s elder brother Frederick III succeeded him in Ansbach from 1625 onwards, initially under their mother"s guardianship, but he was killed without issue in the Thirty Years" War in 1634. Albert thus succeeded him, though again the early years of his rule were under his mother"s guardianship, only taking up full government responsibilities when his minority ended in 1639. With much diplomatic skill, he manoeuvred Brandenburg-Ansbach through the last ten years of the war and through administrative reforms, support for the guilds and cultural life and a good cr policy he promoted the beginnings of post-war reconstruction.
He offered refuge to religious refugees from Austria and in 1647 or 1662 granted them lands in Treuchtlingen and Berolzheim.
Albert"s main advisor on this was his former teacher Johannes Limnäus. Active in the politics of the Holy Roman Empire, he sent troops to back the war against the Ottoman Empire.
A typical Baroque absolute ruler, he died at Ansbach in 1667. He was buried in the Johanniskirche in that city.
