Final answer:
Margaret of Burgundy used Maximillian's disappointment at the Treaty of Etaples to further her own political agenda and gain support for her family's interests.
Step-by-step explanation:
Margaret of Burgundy used Maximillian's disappointment at the Treaty of Etaples to further her own political agenda and gain support for her family's interests. The Treaty of Etaples, signed in 1492, was a peace agreement between England and France that brought an end to the Hundred Years' War. However, Emperor Maximillian I of Austria felt that the treaty did not sufficiently protect his wife, Margaret's sister, Mary of Burgundy, who had recently passed away.
Margaret of Burgundy capitalized on Maximillian's disappointment by stirring up anti-French sentiment and encouraging Maximillian to pursue a more aggressive stance towards France. She used her influence to convince Maximillian to support various anti-French coalitions and alliances, including the League of Venice. Through these alliances, Margaret sought to undermine French power and regain control over Burgundian territories that had been lost in previous conflicts.
By manipulating Maximillian's disappointment and leveraging it to her advantage, Margaret of Burgundy played a significant role in shaping the political landscape of Europe during this period.
