Nicholas IV Mouzalon (

Patriarch of Constantinople
from December 1147 to March/April 1151.

Nicholas was born in c. 1070, and probably began his career teaching the

Kosmidion suburb of Constantinople
.

He was elected to the patriarchal throne in 1147, replacing

Cosmas II, who was accused of Bogomilism. His election however caused considerable controversy: its canonical validity
was called in question, since he had voluntarily resigned from his previous see. Eventually, Nicholas was forced to resign as patriarch, and died in 1152.

He wrote a number of theological works, amongst them a treatise refuting the Filioque addressed to Alexios I, and a vivid poetic defence of his first abdication.
