Styria

Styria was a duchy of the Holy Roman Empire centred on Graz. The Habsburgs acquired it after defeating Ottokar II of Bohemia in 1278 and still ruled it in 1337.

The Treaty of Neuberg gave Styria to Leopold III's branch of the Habsburgs in 1379; they ruled Inner Austria from Graz. Graz later became a centre of the Counter-Reformation. Ferdinand II expelled Protestants, including astronomer Johannes Kepler in 1600, before inheriting the other Habsburg lands in 1619. Styria became part of the Austrian Empire in 1804.
