Jordan (died in 982 or 984) was the first Bishop of Poland from 968 with his seat, most probably, in Poznań. He was an Italian or German.
Most evidence shows that he was missionary bishop subordinate directly to the Pope. He arrived in Poland, probably from Italy or the Rhineland, in 966 with Doubravka of Bohemia to baptise Mieszko I of Poland. After the death of Jordan until 992 the throne of the Bishop of Poland was vacant, or there was a bishop of unknown name (the first theory is more probable). His successor, from 992, was Unger.
On the basis of his name can only conclude that he came from one of the countries Romance (Italy, France or Lorraine).Jan Dlugosz considered him a Roman of the family Orsini, however, provides no historical support for this. A certain popularity in the literature enjoys ejected by Wladyslaw Abraham hypothesis about the origin of the Diocese leodyjskiej in Lorraine (now Liege in Belgium). Another hypothesis assumes that could be Italian with the Patriarchate of Aquileia, which included its jurisdiction over the Slav peoples in the north-western Balkans. Regardless of nationality, it is likely he had a relationship with the Roman Catholic Diocese of Regensburg, which were subject to the Czech Republic. Probably belonged to the Benedictine order, though sources anywhere do not explicitly state this.
A reconstruction activities Jordan is largely based on guesswork. Some historians believe he was originally a priest accompanying Dobrawie, in 966 to Mieszko I, or that he was an auxiliary bishop of the diocese of Regensburg, which were subject to the Czech Republic, (this is disputed by some) or a monk sent to the Polish mission directly by the emperor.
