マルグリット・ド・ヴァロワ
The Treaty of Adrianople, signed in February 1568, concluded the first war between the Ottoman Empire and the Habsburgs. According to the treaty, John Sigismund retained all territories that he had conquered from Maximilian II in the previous years. The envoy of the Ottoman Sultan Selim II in Paris suggested that John Sigismund should marry Margaret of Valois, but his proposal was ignored.
