Crusader–Fatimid wars s c. 1140 Ascalon was an important fortress of the Egyptian
Fatimid Caliphate in
Palestine. The
Battle of Ascalon was fought outside the city in 1099 in the aftermath of the
First Crusade and the
capture of Jerusalem by the
Crusaders from the Fatimids. Although the Crusaders defeated the Fatimid army, internal disputes in their camp allowed Ascalon to remain in Egyptian hands. Thereafter, the Fatimids were able to launch frequent raids into the kingdom from this fortress, and it also served as staging ground for larger Egyptian invasions of Jerusalem (such as in
1101,
1102, and
1105). No invasions occurred after 1123, but there were continued raids from Ascalon against Jerusalem and by the Fatimid navy against coastal cities. The southern border of the kingdom and the roads taken by Christian pilgrims to the Holy Land remained unstable because of this. The Fatimid garrison in Ascalon received regular supplies from Egypt and was considered too strong for King
Baldwin I of Jerusalem to attack it during the 1110s. The Fatimids considered the fortress to be a bulwark against a Crusader invasion of Egypt. During the 1130s and 1140s a series of fortresses were built to watch Ascalon and defend the kingdom's southern border. These were
Ibelin (Yibneh) about northeast of Ascalon near the coast, Blanchegarde (
Tell es-Safi) about to the northeast, Beth Gibelin (
Bayt Jibrin) about to the east and
Montgisard near
Ramla, nearly to the northeast. Around 1149–1150,
Baldwin III of Jerusalem rebuilt part of the fortifications of
Gaza City, which at that point lay in ruins, south of Ascalon. This ring of forts cut off Ascalon from overland supply routes, forcing the Fatimids to keep the city supplied by sea. The Christian
military orders were also becoming more prominent in the defense of Jerusalem. Gaza was given to the
Knights Templar and Beth Gibelin had already been entrusted to the
Knights Hospitaller in 1136. These were the first major castles that each order received.
Second Crusade The Second Crusade occurred after the Crusader city of
Edessa fell to the
Seljuk Turkic forces of
Imad al-Din Zengi in 1144. Zengi's expansionism out of northern
Syria around that time also led the
emir of Damascus,
Mujir ad-Din, to conclude an alliance with the Kingdom of Jerusalem in 1140 to protect his independence. But after Zengi died, his successor
Nur ad-Din of
Aleppo was initially seen as less of a threat to Damascus than the
Latin Christians. Mujir concluded an alliance with Nur in 1147, which contributed to the decision of the Crusaders to
besiege Damascus in 1148, as the Kingdom of Jerusalem could be threatened by a unified Muslim force to its north and east. But the Syrian campaign of the Second Crusade failed, and over the next several years Damascus was gradually brought under the influence of Nur ad-Din. Mujir continued to keep Damascus independent, and still cooperated with the Kingdom of Jerusalem on some occasions, though he and the city's population became more closely aligned with Nur. The Crusaders' decision to attack Damascus strengthened the position of Nur ad-Din in Syria. In 1149 Nur defeated another Crusader state to the north of Jerusalem, the
Principality of Antioch, and killed its ruler
Prince Raymond at the
Battle of Inab. The arrival of reinforcements in the form of King
Baldwin III of Jerusalem and a company of Knights Templar led to a truce between Nur and the Principality of Antioch, which was left with
Antioch itself and the coastal plain between
Alexandretta and
Latakia. With Nur ad-Din becoming more powerful to the north and east of Jerusalem, the Crusader kingdom looked south toward the Fatimid Caliphate in Egypt, which was divided by internal power struggles at the time. King Baldwin wanted to offset his defeats in the north by winning victories over the Muslims to the south. The Fatimid fortress at Ascalon was the last coastal city in Palestine still holding out against the Crusaders after the
capture of
Tyre in 1124.
Prelude The Fatimid Caliphate had been unstable since the assassination of
Al-Afdal Shahanshah, the powerful
vizier of Egypt, and several of his successors, both
caliphs and viziers, were also murdered over the next several decades. In 1150 King Baldwin rebuilt the defenses of Gaza, in preparation for an attack against Ascalon. In response to this the Egyptian vizier
Ibn al-Sallar sent
Usama ibn Munqidh to make an alliance with Nur ad-Din and organize an attack against the Crusaders, but Nur ad-Din refused, because he was focused on Damascus. Usama then stayed at Ascalon for two years and took part in fighting the Crusaders in the area. The Crusader army was also able to bypass the city to carry out limited raids into Egyptian territory. Muslim sources noted a Crusader attack against the town of
al-Farama in 1150, located on the edge of the
Nile Delta, and in the following year the Fatimids launched naval raids against port cities in Palestine. However, Jerusalem itself was soon divided by civil war. Baldwin III was the legal heir to the kingdom, but his mother Queen
Melisende had been ruling as regent. In April 1152 Baldwin wanted to be crowned as king, but his mother insisted on being crowned again with him, so that her continued authority was recognized. Instead of allowing this, Baldwin went to the
Church of the Holy Sepulchre and forced the
Patriarch of Jerusalem to only given the crown to him. The majority of the kingdom's nobility supported the Queen, and a royal council divided the kingdom, with
Galilee being controlled by King Baldwin and the south, including
Nablus and Jerusalem, by Queen Melisende. Their quarrel was eventually resolved and the kingdom reunited, though not before a Seljuk Turkish prince, Timurtash of Mardin, tried to take advantage of the civil war by attacking towards Jerusalem from Mujir ad-Din's territory. But the Crusader garrison of Jerusalem ventured out and defeated the Seljuk army when it was encamped at the
Mount of Olives. == The siege begins ==
