Amalric of Jerusalem
Amalric (113611 July 1174) was King of Jerusalem from 1163, and Count of Jaffa and Ascalon before his accession.
He was the second son of Melisende and Fulk of Jerusalem, and succeeded his older brother Baldwin III.
During his reign, Jerusalem became more closely allied with the Byzantine Empire, and the two states launched an unsuccessful invasion of Egypt.
Meanwhile, the Muslim territories surrounding Jerusalem began to be united under Nur ad-Din and later Saladin.
He was the father of three future rulers of Jerusalem, Sibylla, Baldwin IV, and Isabella I.
Older scholarship mistook the two names Amalric and Aimery as variant spellings of the same name, so these historians erroneously added numbers, making Amalric to be Amalric I (1163–74) and King Aimery (1197–1205) to be "Amalric II".
Now scholars recognize that the two names were not the same and no longer add the number for either king.
Confusion between the two names was common even among contemporaries.
