THE MEDIEVAL WORLD
The Just War
Pope Urban readily seized a cause
that would enhance papal prestige.
In a sermon of 1095, he described
atrocities against Christians in the
Holy Land, calling for an expedition
to free them. Christian warriors
rallied to the cause, eager to gain
both salvation and plunder by joining
a so-called Just War in God’s name.
Some 100,000 crusading knights,
mostly French and Norman, set out
in 1096. Progress to Jerusalem was
slow: the crusaders suffered several
setbacks at the hands of the Seljuk
Turks, and the long siege of Antioch
severely tested their morale, yet
they pressed on and, led by the
French knight Godfrey of Bouillon,
at last captured the Holy City.
In the area they had conquered,
the crusaders established four
states, at Edessa, Antioch, Tripoli,
and the Kingdom of Jerusalem,
known collectively as Outremer.
To withstand the vigorous Muslim
counter-attacks, the crusaders built
a dense network of fortresses such
as Beaufort, Margat, and Krak
des Chevaliers, which dominated
strategic routes into the Holy Land.
As the initial crusading impulse
waned, Outremer began to suffer
from a shortage of manpower. This
was partly resolved by the founding
of crusading orders such as the
Templars and Hospitaller knights,
organizations who swore monastic
vows to defend the Holy Land.
Further Crusades
However, even this was not
enough, and when Muslim armies
captured Edessa in 1144, a Second
Crusade was called. This, and the
Emperor Alexios appeals
for help to defend the
Byzantine Empire.
Further crusades are
launched to defend the
crusader states against
Muslim counter-attacks.
Pope Urban II calls
upon Christian
knights to launch a
military expedition
to Jerusalem.
The crusading
movement spreads
to eastern Europe and
southern France.
Crusading
armies capture
Jerusalem and
establish states
in Palestine
and Syria.
Third Crusade mustered in
response to the catastrophic loss
of Jerusalem in 1187, attracted
participation at an even higher
level, as monarchs such as Louis
VIII of France, Richard I of England,
and the Holy Roman Emperor
Frederick Barbarossa assumed
their leadership.
By 1270 there had been eight
further crusades, and the movement
had extended to include attacks on
Muslims in North Africa; joining
the Reconquista (the Christian
reconquest of Islamic emirates
in Spain); launching expeditions
against pagan groups in eastern
Europe, and even Christian heretics,
such as the Cathars in southern
France. In the Middle East, however,
the emergence of stronger Muslim
states, such as the Mamluks in
Egypt, able to mount a strong
resistance to crusader pressure,
rendered the later expeditions
largely ineffectual.
Jerusalem fell to the Muslims
for a final time in 1244. The last
crusader stronghold in the Holy
Land, the city of Acre, was taken
by the Mamluks in 1291. ■
A race absolutely
alien to God has invaded
the land of Christians, has
reduced the people with
sword, rapine, and flame.
