The County of Zweibrücken-Bitsch (, ) was a territory of the Holy Roman Empire that was created between 1286 and 1302 from the eastern part of the County of Zweibrücken and the Barony of Bitche () in Lorraine. It continued to exist until 1570 and was then divided amongst its heirs when the counts died out. History When the land of Zweibrücken was divided amongst the sons of Count Henry II of Zweibrücken, the district (Amt) of Lemberg and Lemberg Castle went to the elder son, Eberhard I from 1286. His portion also included Morsberg, Linder and Saargemünd. In 1297 he swapped these three castles with Duke Frederick III of Lorraine and received in return the castle and lordship of Bitsch as a fief. This exchange of territory was further defined in 1302. From then on, Eberhard called himself the Count of Zweibrücken and Lord of Bitsch. Because he and his descendants bore the comital title, the new territory was called the County of Zweibrücken-Bitsch. Other lands were initially managed jointly by Eberhard I and his younger brother, Walram I, who had been given the Amt of Zweibrücken. These were not finally apportioned until 1333. Walram inherited Stauf Castle, Bergzabern and the town and abbey of Hornbach. Eberhard received Thaleischweiler, Pirmasens and part-ownership of the castles of Landeck and Lindelbronn. In the period that followed the counts of Bitsch succeeded in acquiring a few other properties, but only in the immediate vicinity. When their Zweibrücken cousins died out in 1394, they did receive parts of the inheritance, but not the County of Zweibrücken because the last count had sold his county in 1385 to Electoral Palatinate. In the 16th century, Count James succeeded for the last time in establishing a clear concentration of power in northern Alsace and southern Palatinate: in 1559 he obtained the Barony of Ochsenstein because the side line of Zweibrücken-Bitsch-Ochsenstein, that had existed since 1485, had died out. Because, however, James as well as his brother Simon V Wecker (died 1540) had each only produced a daughter, a dispute broke out in 1570 after James' death between the husbands of the two cousins, Count Philip I of Leiningen-Westerburg and Count Philip V of Hanau-Lichtenberg. Whilst Philip V of Hanau-Lichtenberg was able to overpower Philip I, his immediate introduction of Lutheranism in the course of the Reformation made himself an enemy of the powerful, Roman Catholic Duchy
