completing the Reconquista. It also
put an end to centuries of Christian
infighting, and this unity coincided
with a period of Muslim division.
From 1482, the monarchs undertook
a series of military campaigns to
conquer Granada—the last Muslim
the 12th century, military orders,
such as Santiago and Alcántara,
were founded. They frequently
spearheaded independent thrusts
into Muslim territory, amassing
great wealth in the process, which
enabled them to sustain extended
campaigns and ransom Christians
taken prisoner in the wars. They
also repopulated land conquered
from the Muslims with Christians.
The end of Muslim Spain
In Portugal, the Reconquista was
completed with the conquest of the
Algarve in 1249, while in Spain the
Muslims clung on to power in the
south. However, this was not to
last. In 1474, Queen Isabella
ascended to the throne of Castile,
in northern Spain. Her husband
Ferdinand was already king of the
neighboring state of Aragón, and
they resolved to permanently expel
the Muslims from the south. The
union of the two crowns enabled
them to devote more resources to
emirate in the Iberian peninsula.
The cities were put under siege and
fell one by one, until finally the major
city of Granada surrendered in 1492.
Despite an agreement reached
at the capitulation of Granada,
which contained guarantees for
freedom of worship, in 1502 the
monarchs decreed that any Muslims
over the age of 14 who refused to
convert to Christianity must leave
Spain within 11 weeks. This edict,
combined with the expulsion of the
large Jewish community in Granada
10 years earlier, left Spain a more
homogeneous and less tolerant
place, and the crusading impulse,
now shorn of obvious targets, would
have to find other channels.
Christopher Columbus’s
expedition to the New World in
1492—the same year as the fall of
Granada—provided the Spanish
with just such an outlet, leading to
their colonization of the Americas
and Spain’s subsequent emergence
as the first global superpower. ■
Known as the Catholic Monarchs,
Ferdinand and Isabella joined forces
and used military might to restore
Christianity in Spain, suppress other
religions, and colonize the Americas.
