Christian II of Bolanden (also called Christian II of Wiesenau) (1179 - 1253) was the Archbishop of Mainz from 1249 until 1251. Siegfried III of Eppstein, Archbishop of Mainz, died in 1249 and both Pope Innocent IV and King Henry II announced their desire that Conrad of Hochstaden, Archbishop of Cologne, succeed him. But the cathedral chapter rejected Conrad, preventing two of the most powerful territories in Germany to fall into one's hands. Therefore Pope Innocent IV instead tried to manouvre Henry II of Leiningen, Bishop of Speyer, but the chapter rejected him also and elected Christian instead.
