Johann Clare

Johann Clare (died 5 May 1344), born to a burgher family of Thorn in Prussia, was a Teutonic Order priest who became a Samland canon in 1294 and cathedral dean in 1301.

After Bishop Siegfried of Regenstein died in 1310 the chapter unanimously elected him, but quarrels with Riga's archbishop and the Curia delayed his appointment until Pope John XXII gave him the see in 1319.

From 1320 he sought to recover church rights and lands seized by the order, securing only part of his claims. He oversaw construction of the new Königsberg Cathedral until his death in 1344.
