The relationships among Gediminas' children were generally harmonious, with the notable exception of Jaunutis, who was deposed in 1345 by his brothers Algirdas and Kęstutis. These two brothers went on to provide a celebrated example of peaceful power-sharing. However, Gediminas' many grandchildren and their descendants engaged in power struggles that continued well into the 15th century. Gediminas' grandchildren converted Lithuania to Christianity and inaugurated the first personal union with Poland.
