Margaret, nicknamed Maultasch, was the last Countess of Tyrol from the House of Gorizia (Meinhardiner), and an unsuccessful claimant to the Duchy of Carinthia. Upon her death, Tyrol became united with the Austrian hereditary lands of the Habsburg dynasty.

The (Princely) County of Tyrol was an estate of the Holy Roman Empire established about 1140. After 1253, it was ruled by the House of Gorizia and from 1363 by the House of Habsburg. In 1804, the County of Tyrol, unified with the secularised prince-bishoprics of Trent and Brixen, became a crown land of the Austrian Empire. From 1867, it was a Cisleithanian crown land of Austria-Hungary.
