Władysław II Jagiello and Jadwiga reigned as co-monarchs; and though Jadwiga probably had little real power, she took an active part in Poland's political and cultural life. In 1387, she led two successful military expeditions to Red Ruthenia, recovered lands her father, Louis I of Hungary, had transferred from Poland to Hungary, and secured the homage of Voivode Petru I of Moldavia. In 1390, she also personally opened negotiations with the Teutonic Order. Most political responsibilities, however, fell to Jagiello, with Jadwiga attending to the cultural and charitable activities for which she is still revered.
