Everyone is Muslim

Islam is the dominant religion in Central Asia with 90% of the population in Turkmenistan, Tajikistan, and Uzbekistan being Muslim, with Kyrgyzstan and Kazakhstan not far behind. However, there are other religions in Central Asia, namely Buddhism, Christianity, Bukharan Jews, Zoroastrianism, Tengrism and Nestorianism.

Buddhism spread to Central Asia from the northwest of the Indian subcontinent and thrived there until the eleventh century, especially with the support of the Uighur Turks.

Speaking about Christianity, it is still a minority religion in the Central Asia region today because of the advent of Islam in the ninth century. There are two groups of Christianity: Western and Eastern. Nestorian Christianity is also present in Central Asia and it has a small difference in religious belief to Christianity. Since every one of the countries in Central Asia currently has a small population in comparison to Islam, Christian churches there have barely survived.

It is believed that Jews who were driven out of Israel by the Babylonians in 586 B.C. were the first Jews to settle in Central Asia. Just about 100–200 Jews exist in Uzbekistan and Tajikistan now, and the rest are either "Bukharan" or live elsewhere in Central Asia.

The religion of Zoroastrianism was founded in the sixth century B.C., and it was brought to Central Asia in the second century A.D. The conflict between good and evil, light and darkness, and human responsibility are the main religious belief.

Tengrism is now mostly combined with Islam as their legends are partly associated with Islam. Today, the presence of this religion may be found in Kazakhstan.
