Bayan-Ölgii Province in the context of "Ölgii (city)"

The Kazakhs are a Turkic ethnic group native to Central Asia and Eastern Europe. They share a common culture, language and history that is closely related to those of other Turkic peoples. The majority of ethnic Kazakhs live in their transcontinental nation state of Kazakhstan.

Ethnic Kazakh communities are present in Kazakhstan's border regions in Russia, Kyrgyzstan, northern Uzbekistan, northwestern China (Xinjiang), western Mongolia (Bayan-Ölgii), and northern Iran (Golestan). The Kazakhs arose from the merging of various medieval tribes of Turkic and Mongolic origin in the 15th century.

Kazakh is a Turkic language of the Kipchak branch spoken in Central Asia by the Kazakhs. It is closely related to Nogai, Kyrgyz and Karakalpak. It is the official language of Kazakhstan, and has official status in the Altai Republic of Russia. It is also a minority language in the Ili Kazakh Autonomous Prefecture in Xinjiang, China, and in the Bayan-Ölgii Province of western Mongolia. The language is also spoken by many ethnic Kazakhs throughout the former Soviet Union (some 472,000 in Russia according to the 2010 Russian census), Germany, and Turkey.

Like other Turkic languages, Kazakh is an agglutinative language and employs vowel harmony. Kazakh builds words by adding suffixes one after another to the word stem, with each suffix expressing only one unique meaning and following a fixed sequence. Ethnologue recognizes three mutually intelligible dialect groups: Northeastern Kazakh—the most widely spoken variety, which also serves as the basis for the official language—Southern Kazakh, and Western Kazakh. The language shares a degree of mutual intelligibility with the closely related Karakalpak language while its Western dialects maintain limited mutual intelligibility with the Altai languages.

The Great Lakes Depression, also called the Great Lakes Hollow, is a large semi-arid depression in Mongolia that covers parts of the Uvs, Khovd, Bayan-Ölgii, Zavkhan and Govi-Altai aimags. Bounded by the Altai in the West, Khangai in the East and Tannu-Ola Mountains in the North,it covers the area of over 100,000 km (39,000 sq mi) with elevations from 750 to 2,000 m (2,460–6,560 ft).

Small northern parts of the depression are part of Russia.

Time in Mongolia is officially represented by the Mongolian Standard Time (UTC+08:00). However, the far western provinces of Khovd, Uvs and Bayan-Ölgii use UTC+07:00.

As of 2022, Islam in Mongolia, is practiced by approximately 5.4% of those who identify with a religion, according to the USCIRF. Given that 59.4 percent of the population reported having a religious identity in the 2020 census, Muslims constitute roughly 3.2 percent of the total population It is practised by the ethnic Kazakhs of Bayan-Ölgii Province (88.7% of total aimag population) and Khovd Province (11.5% of total aimag population, living primarily in the Khovd city, Khovd district, and Buyant district) in western Mongolia. In addition, a number of small Kazakh communities can be found in various cities and towns spread throughout the country. Islam is also practiced by the smaller communities of Khotons and Uyghurs.

Some Mongolian Muslims fused elements from Buddhism into their beliefs, even thinking of the Buddha as synonymous to Adam, the first prophet in Islam, although this does not happen in modern times.
