Arab Religions - Arabs are an ethnic group that exhibits religious diversity, though the vast majority of them are Sunni Muslims.

(The following mateial is evidence of the religious diversity, but you do not need to memorize it:  Most Arabs are Muslim (followers of Islam), but the majority of the world's Muslims live in South Asia, not the Middle East. Middle Eastern countries such as Lebanon and Syria are religiously diverse and are home to Sunni and Shi'ite Muslims, Christians and Roman Catholics, as well as Druze and Alawite communities, which are offshoots of Islam.

Lebanon has a large Christian population that includes Maronite and Melkite Catholics, and Greek and Armenian Orthodox communities. The country recognizes 18 different religions.

Perhaps as much as one tenth of Egyptians are Coptic Christians, a denomination founded in the early orthodox Christian church.)

Persians/Iranians - Persians are an ethnic group that exhibits religious diversity, though the vast majority of them are Shi'a Muslims.

(The following mateial is evidence of the religious diversity, but you do not need to memorize it:  Although the vast majority of Iranians are Shi'a Muslims, important religious minorities have always played an important role in Iranian life. Zoroastrians date back more than two thousand years ago. Iranian Jews claim to be the oldest continuous Jewish community in the world, dating back to the removal to Babylon. Armenians, an ancient Christian people, were imported by Iranian rulers for their artisanry, and Assyrian Christians have been continually resident in Iran since the third century.

Sunni Muslims are represented by Arab and Baluchi populations in the south and Turkish populations in the north and west. One religious group is homegrown. The Baha'i movement, a semi-mystical nineteenth-century departure from Shi'ia Islam, won converts not only from Islam, but also from Judaism, Zoroastrianism, and Christianity. Considered a heresy by many Shi'a Muslims, Baha'i has spread from Iran to virtually every nation on earth.)

Kurds (an ethnic grup)

The Kurds are a non-Arabic people who largely adhere to the Sunni Muslim faith. A people with their own language and culture, most Kurds live in the generally contiguous areas of Turkey, Iraq, Iran, Armenia and Syria – a mountainous region of southwest Asia generally known as Kurdistan ("Land of the Kurds").
