- from Muslim Empires
The Ottoman Empire was at full power in the early 1500s. Around then, a group of Muslims called the Safavids (sah-FAH-weeds) took over Persia. (Persia is now Iran.)
The Safavids waged war on lands east of the Ottoman Empire. But their desire for conquest led to conflict with the Ottomans. It wasn’t just about control of territory. The Ottomans and Safavids had different beliefs, even though both groups followed Islam.
The conflict was based on an old argument Muslims had. The argument was about who should be allowed to become caliph. In the mid-600s, Islam split into two groups because of this argument. The Shia (SHEE-ah) was one group. They thought only Muhammad’s descendants could become caliphs. The Sunni (SOO-nee) was the other group. They didn’t believe caliphs had to be related to Muhammad. Safavid leaders were Shia. And the Ottomans were Sunni. As the Safavids began pushing into new territory, the Ottomans were set on keeping Shia beliefs from spreading.
