What were the crusades and what was their purpose

After centuries of Muslim expansion, western European Christians created the Crusades. Their main goals were to halt Muslim state expansion, regain the Holy Land in the Middle East for Christianity, and retake lands that had previously been Christian. Many participants also felt that engaging in what they considered as holy war would provide them with redemption and atone for their sins.

the most famous of all the units fighting in cuba, the "rough riders" was the name given to the first u.s. volunteer cavalry under the leadership of theodore roosevelt. roosevelt resigned his position as assistant secretary of the navy in may 1898 to join the volunteer cavalry. the original plan for this unit called for filling it with men from the indian territory, new mexico, arizona, and oklahoma. however, once roosevelt joined the group, it quickly became the place for a mix of troops ranging from ivy league athletes to glee-club singers to texas rangers and indians.
