Heinrich Raspe

Landgraf of Thuringia and anti-king of the Holy Roman Empire from 1246 at the pope's instigation. He was banished from the court by his nephew Hermann II and his mother Elisabeth. He was nominated regent for the minor Konrad IV, whom he conquered at the battle of the Nidda on 5 August 1246.

In Thuringia, Heinrich initially was regent for his under-age nephew Hermann II, but he managed to expel his nephew and the boy's mother from the line of succession and in about 1231 formally succeeded his brother Ludwig IV, who had died on a crusade, as landgrave.

In 1242 Heinrich, together with King Wenceslaus I of Bohemia, was selected by Emperor Friedrich II to be administrator of Germany for Frederick's under-age son Konrad (Conrad IV).
