The 'Seventh Crusade' was a
crusade led by
Louis IX of France from
1248 to
1254.
Background
In
1244, shortly after the expiry of the ten-year truce of the
Sixth Crusade, the
Khwarezmians retook
Jerusalem. The fall of Jerusalem was no longer an earth-shattering event to
European
Christians, who had seen the city pass from Christian to
Muslim control numerous times in the past two centuries. This time, there was no popular enthusiasm for a new crusade.
Pope Innocent IV and
Frederick II, Holy Roman Emperor continued the papal-imperial struggle. Frederick had captured and imprisoned clerics on their way to the
Council of Lyons, and in 1245 he was formally deposed by Innocent IV.
Pope Gregory IX had also earlier offered King Louis' brother, count
Robert of Artois, the German throne, but Louis had refused. Thus, the
Holy Roman Emperor was in no position to crusade.
Henry III of England was still struggling with
Simon de Montfort and other problems in
England. Henry and Louis were not on the best of terms, being engaged in the Capetian-
Plantagenet struggle, and while Louis was away on crusade the English king signed a truce promising not to attack French lands. Louis IX had also invited King
Haakon IV of Norway to crusade, sending the English chronicler
Matthew Paris as an ambassador, but again was unsuccessful. The only man interested in beginning another crusade therefore was Louis IX, who declared his intent to go East in
1245.
The crusade
France was perhaps the strongest state in Europe at the time, as the
Albigensian Crusade had brought
Provence into
Parisian control.
Toulouse was led by Louis IX's brother
Alphonse, who joined him on his crusade in 1245. Another brother,
Charles I of Anjou, also joined Louis. For the next three years Louis collected an ecclesiastical tenth (mostly from
church tithes), and in
1248 he and his approximately 15-25,000-strong army that included 1,500 knights, and 5,000 crossbowmen sailed from the ports of
Aigues-Mortes, which had been specifically built to prepare for the crusade, and
Marseille. Louis IX's financial preparations for this expedition were comparatively well organised, and he was able to raise approximately 1,500,000 livres tournois. However, many nobles who joined Louis on the expedition had to borrow money from the royal treasury, and the crusade turned out to be very expensive.
They sailed first to
Cyprus and spent the winter on the island, negotiating with various other powers in the east; the
Latin Empire set up after the
Fourth Crusade asked for his help against the
Byzantine Empire of Nicaea, and the
Principality of Antioch and the
Knights Templar wanted his help in
Syria, where the Muslims had recently captured
Sidon.
Nonetheless,
Egypt was the object of his crusade, and he landed in
1249 at
Damietta on the
Nile. Egypt would, Louis thought, provide a base from which to attack Jerusalem, and its wealth and supply of grain would keep the crusaders fed and equipped.

Louis IX attacks Damietta
On
June 6 Damietta was taken with little resistance from the Egyptians, who withdrew further up the
Nile. The flooding of the Nile had not been taken into account, however, and it soon grounded Louis and his army at Damietta for six months, where the knights sat back and enjoyed the spoils of war. Louis ignored the agreement made during the
Fifth Crusade that Damietta should be given to the
Kingdom of Jerusalem, now a rump state in Acre, but he did set up an archbishopric there (under the authority of the
Latin Patriarch of Jerusalem) and used the city as a base to direct military operations against the Muslims of Syria.
In November, Louis marched towards
Cairo, and almost at the same time, the
Ayyubid sultan of Egypt,
as-Salih Ayyub, died. A force led by
Robert of Artois and the Templars attacked the Egyptian camp at
al-Mansourah, but they were defeated and Robert was killed. Meanwhile, Louis' main force was attacked by the
Mameluk Baibars, the commander of the army and a future sultan himself. Louis was defeated as well, but he did not withdraw to Damietta for months, preferring to besiege Mansourah, which ended in starvation and death for the crusaders rather than the Muslims. In March of
1250 Louis finally returned to Damietta, but he was taken captive on the way there, fell ill with dysentery, and was cured by an Arab physician. In May he was ransomed in return for Damietta and 400,000 livres, and he immediately left Egypt for
Acre, one of few remaining crusader possessions in Syria. Meanwhile, the Mameluk soldiers of Egypt revolted.
Turanshah, as-Salih's successor, took control of Cairo, creating a Mameluk dynasty destined to conquer the last of the crusader territories.
Resolution
Louis made an alliance with the Mameluks, and from his new base in Acre began to rebuild the other crusader cities. Although the
Kingdom of Cyprus claimed authority there, Louis was the ''de facto'' ruler. Louis also negotiated with the
Mongols, who had begun to appear in the east and who the Christians, encouraged by legends of a
Nestorian kingdom among them (cf.
Prester John), hoped would help them fight the Muslims and restore the
Crusader States. They, like the Muslims who were similarly negotiating with the Mongols against the Christians, were unaware that the Mongols were not interested in helping either side and would eventually be disastrous for both. Louis' embassy to the Mongol ruler
Möngke Khan, headed by
William of Rubruck, was a failure. The Khan rejected Louis' invitation to convert to Christianity, and instead suggested Louis submit to him.
In
1254 Louis' money ran out, and his presence was needed in France where his mother and regent
Blanche of Castile had recently died. His crusade was a failure, but he was considered a
saint by many, and his fame gave him an even greater authority in Europe than the
Holy Roman Emperor. In
1270 he attempted
another crusade, though it too would end in failure.
The history of the Seventh Crusade was written by
Jean de Joinville, who was also a participant.
