Amalric I of Jerusalem vs Fulk of Jerusalem

Amalric I launched an invasion of Fatimid Egypt, aiming to exploit internal divisions. He captured the city of Bilbeis but was forced to withdraw after Nur ad-Din sent reinforcements. This began a series of campaigns for control of Egypt.

Amalric I succeeded his brother Baldwin III as King of Jerusalem. He inherited a kingdom facing threats from Nur ad-Din Zengi and the Fatimid Caliphate, and immediately began planning campaigns to expand crusader influence.

Amalric I negotiated an alliance with Byzantine Emperor Manuel I Komnenos, agreeing to a joint campaign against Egypt. The alliance included a marriage between Amalric and Maria Komnene, and promised Byzantine naval support.

Amalric I and Byzantine forces launched a joint siege of Damietta in Egypt. The campaign failed due to poor coordination, supply issues, and the arrival of Nur ad-Din's army. This defeat ended crusader hopes of conquering Egypt.

Amalric I died of dysentery at age 38, leaving his young son Baldwin IV as heir. His death weakened the Kingdom of Jerusalem, as it faced the rising power of Saladin, who had united Egypt and Syria.

Fulk inherited the County of Anjou from his father Fulk IV. He became a powerful French noble, known for his military skill and political maneuvering.

Fulk married Melisende, daughter of King Baldwin II of Jerusalem. The marriage made him heir to the Kingdom of Jerusalem and strengthened ties between the Crusader states and Europe.

Fulk was crowned King of Jerusalem alongside his wife Melisende. He became the ruler of the Crusader kingdom, facing threats from Muslim states to the north and east.

Fulk led campaigns against the Muslim ruler Zengi of Mosul. He successfully defended the kingdom's borders, but failed to capture key cities like Damascus.

Fulk died after falling from his horse during a hunting trip near Acre. His death left the kingdom in the hands of his wife Melisende and their son Baldwin III.
