Gertrude was born in
Deilingen,
Swabia to Count Burkhard V of Hohenberg (died 1253) and his wife Matilda (
Mechtild), daughter of Count Palatine
Rudolf II of Tübingen. The comital
Hohenberg dynasty, a cadet branch of the Swabian
House of Hohenzollern, then ruled over extended estates in southwestern
Germany. Citing contemporary sources, Gertrude's descent was questioned by the
Swiss historian
Aegidius Tschudi (1505–1572), who postulated a
Frohburg lineage; nevertheless, his objections have been disproved. About 1253/4, Gertrude married Rudolf (1218–1291), son of Count
Albert IV of Habsburg and Heilwig of
Kyburg. She went on to live with her husband as a comital couple in
Rheinfelden. They had eleven children. Gertrude's husband was elected
King of the Romans (as Rudolf I) in
Frankfurt on 29 September 1273. The election was largely due to the efforts of her cousin Burgrave
Frederick III of Nuremberg. Rudolf was crowned in
Aachen Cathedral on 24 October 1273. After the coronation of the noble couple, she called herself Queen Anne. As "Queen Anne" (
Anna Regina) she served as his consort for the following eight years. Reluctant to interfere in politics, she witnessed Rudolf's struggles to secure his rule against the rivalling King
Ottokar II of Bohemia, as well as his fruitless efforts to be crowned
Holy Roman Emperor. Gertrude died on 16 February 1281 at her husband's residence in
Vienna. According to her will, she was buried in
Basel Minster, alongside her youngest son Charles. King Rudolf had been engaged in lengthy conflicts with the
Prince-Bishops of Basel before his coronation, and Queen Anne wish to be buried in Basel provided him with an opportunity to mend ties with the citizens of Basel. He gave his consent to the funeral in Basel which took place on 20 March. Her entrails were taken out and her body was filled with sand before the burial. Centuries later, her mortal remains were solemnly transferred to
Saint Blaise Abbey in 1770; today they rest at
Saint Paul's Abbey in
Carinthia. King Rudolf remained a widower for three years and proceeded to marry
Isabella of Burgundy. ==Issue==
