Albert IV, Count of Habsburg

He was the son of Count Rudolph II of Habsburg and Agnes of Staufen.

About 1217, Albert married Hedwig (Heilwig),[1] daughter of Count Ulrich of Kyburg (died 1237) and Anna of Zähringen.

Upon the death of his father in 1232, he divided his family's estates with his brother Rudolph III, whereby he retained the ancestral seat at Habsburg Castle.

A follower of Emperor Frederick II of Hohenstaufen, he took part in the Barons' Crusade of 1239 with King Theobald I of Navarre and died near Ashkelon.

[2] A cause for Albert's beatification in the Catholic Church was opened on 4 September 1908, and he was declared a Servant of God.
