Jelena's regency ended in 1357. She and her sons were granted citizenship by the Republic of Venice in 1364. Two years later she accompanied Tvrtko to the Hungarian royal court following his brief deposition in favor of Vuk; Tvrtko reinstated himself within a year.[4] In the fall of 1374, Jelena organized and attended the wedding of her son and Dorothea of Bulgaria.[citation needed]
