Origin
Meaning and origin of Ilyasov
The surname ILYASOV originated from the Russian patronymic naming system, which was widely used in the Russian Empire and the Soviet Union. It is derived from the masculine given name Ilyas, which is the Russian version of the Arabic name Ilyas or Elijah.
ILYASOV likely emerged in the late 19th or early 20th century as Russian surnames were formalized and standardized. The patronymic suffix "-ov" was added to the name Ilyas, indicating "son of Ilyas." This naming convention was common among Russians, particularly those of Muslim heritage from regions like the Volga-Ural area, Caucasus, and Central Asia.
The name's origins can be traced back to the spread of Islam in the region and the influence of Arabic and Persian cultures. The name Ilyas is a prominent figure in Islamic tradition, being one of the prophets mentioned in the Quran.
One of the earliest recorded instances of the surname ILYASOV can be found in the 1897 census of the Russian Empire, where several families with this surname were registered in the Kazan Governorate, a region with a significant Tatar and Bashkir population.
Notable individuals with the surname ILYASOV include:
1. Abdulkhak Ilyasov (1913-1998), a Soviet and Russian writer and playwright of Tatar descent, known for his works depicting the life and culture of the Tatar people.

5. Jamil Ilyasov (1914-1997), a Soviet and Russian film director and screenwriter, known for his contributions to the Tatar cinema.

When a category has too few respondents for a given surname, the Bureau suppresses the figure to protect individual privacy, which is why some names show fewer than six slices.
