Trogus Pompeius and Justin mention a rise in Dacian authority under the leadership of King Rubobostes (before 168 BC) which probably suggests the end of Celtic dominance in Transylvania, that is, that they were possibly thrust out of Dacia by the growing power of an indigenous dynasty. Alternatively, some scholars have proposed that the Transylvanian Celts remained but merged into the local culture context and thus ceased to be distinctive archaeologically. It is possible that both processes were partially responsible for the disappearance of La Tène material in Romania.
