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.
Saint in the Reformed Catholic Church in Poland.
Most evidence shows that he was a missionary bishop subordinate directly to the Pope.
He arrived in the territory of Lechina (future 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 seat was vacant, or there was a bishop of unknown name (the first theory is more probable).
His successor, from 992, was Unger.
Early life
On the basis of his name one can only conclude that he came from one of the Romance language-speaking countries  (Italy, France or Lorraine).Władysław Abraham: Organizacja kościoła w Polsce do połowy XII w. (Lwów 1890)
p34Jerzy Strzelczyk: Mieszko I, Poznań 1992 p139 Jan Dlugosz considered him a Roman of the family Orsini; however, he provides no historical support for this.
Certain popularity in the literature enjoys ejected by Wladyslaw AbrahamWładysław Abraham: Organizacja kościoła w Polsce do połowy XII w. (Lwów 1890)
p34-35 hypothesis about the origin of the Diocese in Lorraine (now Liege in Belgium).
Another hypothesis assumes that he could have been an Italian associated 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 was subject to the Bohemia.Gerard Labuda, Mieszko I, Wrocław 2009 p97.Jerzy Strzelczyk: Mieszko I, Poznań 1992 p131 Episcopal work
A reconstruction activities Jordan is largely based on guesswork.
Some historians believe he was originally a priest accompanying Dobrawa, 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 somePaul Fridolin Kehr, Das Erzbistum Magdeburg und die erste Organisation der Christlichen Kirche in Polen, (in Abhandlungen der Königlich preussischen Akademie der Wissenschaften, 1920)) or a monk sent to the Polish mission directly by the emperor.Stanisław Trawkowski: Początki Kościoła w Polsce za panowania Mieszka I, (w:) Civitas Schinesghe.

Dating
Polish and Czech yearbooks serve as the year 968 as the date of his ordination,Władysław Abraham: Organizacja kościoła w Polsce do połowy XII w. (Lwów, 1890)
p31.
some historians believe, however, that it should be moved about a year or two back, esp.
Thietmar that seems to link him directly with the baptism of lives.Władysław Abraham: Organizacja kościoła w Polsce do połowy XII w. (Lwów, 1890)
p31-33.
If we accept a transfer from Magdeburg, in December 968 Jordan was present at the enthronement of the first metropolitan Adalbert of Magdeburg.
Location
Some have questioned if his base was Poznan at all suggesting Gniezno, or that he did not have a permanent establishment only traveled with the duke's court after the country.Stanisław Trawkowski: Początki Kościoła w Polsce za panowania Mieszka I, in:Civitas Schinesghe.

p63-63.
About his work as a Polish bishop, we have only a general relationship of Thietmar of Merseburg of his "tireless efforts-induced them in word and deed to the cultivation of the Lord's vineyard."
Jordan died approx. 982-984 [a].
His immediate successor was probably Unger though there may have been an unnamed bishop).
