Catherine of Savoy
Catherine of Savoy (c. 1298–1336) was a daughter of Count Amadeus V of Savoy and Maria of Brabant. In 1315 she married Leopold I, Duke of Austria and Styria, at Basel, a match tied to Habsburg rapprochement with the House of Luxembourg.
She took an active part in the Habsburgs' efforts to recover the imperial crown after 1308 and corresponded directly with Pope John XXII. Widowed in 1326, Catherine died at Rheinfelden in 1336 and was buried at Königsfelden Monastery.
