<span>It was the Crusades.
The Crusades was a campaign to regain the Holy Land from the Muslim
invaders after they took it over. Some
came to fight for that goal while others joined to see new lands while some
were after the riches that be taken from that area. Many were promised forgiveness of their sins
if they joined the Crusades. Still, some
of the effects of the Crusade were that the Mediterranean was open to trade as
soldiers and markets were established.
Other effects were that it led to the growth of towns and cities as the
nobility sold their lands to join the Crusades and the people gained their
freedom. Finally with the growth of towns, feudalism was weakened.</span>
