8.2 A Muslim Empire

The death of Muhammad plunged his followers into grief. Muhammad had been a pious man and a powerful leader. No one else had ever been able to unify so many Arab tribes. Could the community of Muslims survive without him?

Islam Faces Challenges

Muslims faced a problem when Muhammad died because he had not named a successor to lead the community. Eventually, they agreed that Abu Bakr (uh BOO BAK ur), Muhammad's father-in-law and an early convert to Islam, should be the first caliph, or successor to Muhammad. Abu Bakr sternly told the faithful, “If you worship Muhammad, Muhammad is dead. If you worship God, God is alive.”

Arabs Join Together Under Islam

Abu Bakr faced an immediate crisis. The loyalty of some Arab tribal leaders had been dependent on Muhammad's personal command. They refused to follow Abu Bakr and withdrew their loyalty to Islam. After several battles with the wavering tribes, Abu Bakr succeeded in reuniting the Muslims, based on their allegiance to Islam.

Once reunited, the Muslims set out on a remarkable series of military campaigns. They began by converting the remaining Arab tribes to Islam, which ended warfare between Arabs and united them under one leader.

Arab Muslims Win Victories

Then, under the first four caliphs, the Arab Muslims marched from victory to victory against the neighboring Byzantine and Persian empires, capturing territory in parts of Asia, Europe, and Africa.
