The nobility of this period were highly antagonistic towards each other, and caused problems for Elizabeth and the monarchy. Sicilian magnate families waged a civil war with one another between the 1330s and 1360s. The collective disquiet due to the declining aristocratic incomes culminated in a social and political conflict between them and the throne. Since the nobility controlled the majority of the military force in the kingdom, their rebellion had severe implications towards the throne. From the 1330s until the 1370s, the aristocracy took increasing control of demesne land and towns. The throne's attempts to reduce the power of the nobility was unsuccessful despite Elizabeth's efforts. She proposed a peaceful partition of the country among the most powerful magnate houses in 1350, but it failed after six months. A second attempt was made in 1352, but it too failed after only a year. No final settlement dividing Sicily's administration was reached until the 1360s, after Elizabeth's death. The conclusion was a division of power based on military supremacy between a few feudal states, with the throne retaining little practical influence.
