Amalric I of Jerusalem
The Church of the Nativity was used as the primary coronation church for Crusader kings, from the second ruler of the Latin Kingdom of Jerusalem in 1100 and until 1131. The Crusaders undertook extensive decoration and restoration on the basilica and grounds, a process that continued until 1169, from 1165 to 1169 even through a rare cooperation between the Catholic king Amalric I of Jerusalem and the Byzantine emperor Manuel I Komnenos, who was his uncle.
