Tomislav was succeeded by Trpimir II (928–935), and Krešimir I (935–945), this period, on the whole, however, is obscure. Miroslav (945–949) was killed by his ban Pribina during an internal power struggle, losing part of islands and coastal cities. Krešimir II (949–969) kept particularly good relations with the Dalmatian cities, while his son Stjepan Držislav (969–997) established better relations with the Byzantine Empire and received a formal authority over Dalmatian cities. His three sons, Svetoslav (997–1000), Krešimir III (1000–1030) and Gojslav (1000–1020), opened a violent contest for the throne, weakening the state and further losing control. Krešimir III and his brother Gojslav co-ruled from 1000 until 1020, and attempted to restore control over lost Dalmatian cities now under Venetian control. Krešimir was succeeded by his son Stjepan I (1030–1058), who continued his ambitions of spreading rule over the coastal cities, and during whose rule was established the diocese of Knin between 1040 and 1050 which bishop had the nominal title of "Croatian bishop" (Latin: episcopus Chroatensis).
