Reinhold von Buxhoeveden

Reinhold von Buxhoeveden (died 1557) was bishop of the Bishopric of Saare-Lääne or Ösel–Wiek (Estonian: Saare-Lääne piiskopkond; German: Bistum Ösel–Wiek; Low German: Bisdom Ösel–Wiek; contemporary Latin: Ecclesia Osiliensis), a semi-independent Roman Catholic prince-bishopric in what is now Saare, Hiiu and Lääne counties of Estonia, from 1532 to 1541.

It is not known how long he was in Rome, but upon his departure he was named canon of Tartu and Saare-Lääne dioceses, and no later than 1519 he returned to Livonia.

In 1527, upon the death of Saare-Lääne bishop Johannes IV Kievel, Buxhoeveden should have gained enough influence to be named his successor.

During the Saare-Lääne civil war (1532–1536), Buxhoeveden had to compete with Wilhelm von Hohenzollern, the coadjutant of the archbishop of Riga, who had moved to the Läänemaa region.

Buxhoeveden won out in the end, but at great financial cost, and commitments to the influential families in the Läänemaa vassalage.
