Ovida, Obida or Odiva, was the last Roman ruler of Dalmatia, and a general, of the western provinces, during which late period?
Western Roman Empire In historiography, the Western Roman Empire consists of the western provinces of the Roman Empire at any one time during which they were administered by a separate independent Imperial court, coequal with (or only nominally subordinate to) that administering the eastern half. Both "Western Roman Empire" and "Eastern Roman Empire" (or "Byzantine Empire") are modern terms describing "de facto" independent entities; however, at no point did the Romans consider the Empire split into two, but rather considered it a single state governed by two separate Imperial courts out of administrative expediency. The view that the Empire was impossible to govern by one emperor was established by Diocletian following the disastrous civil wars and disintegration of the Crisis of the 3rd century, and was instituted in Roman law by his introduction of the Tetrarchy in AD 285, a form of government which was legally to endure in one form or another for centuries. The Western Court was periodically abolished and recreated for the next two centuries until final abolition by Zeno in 480, by which time there was little effective central control left in the area legally administered by the Western Court.
Perseus of Macedon Perseus (Greek: Περσεύς, "Perseus"; 212 – 166 BC) was the last king ("Basileus") of the Antigonid dynasty, who ruled the successor state in Macedon created upon the death of Alexander the Great. He also has the distinction of being the last of the line, after losing the Battle of Pydna on 22 June 168 BC; subsequently Macedon came under Roman rule.
