Mazanderani people
The Mazanderani people ( or ) or Tabari people () are an Iranian people who are indigenous to the Caspian region of Iran. They are also referred to as Mazanis for short. They inhabit the southern coast of the Caspian Sea and are part of the historical region known as Tabaristan. The Alborz mountains mark the southern boundary of the area settled by the Mazanderani people. People. The Mazanderani number was 4,480,000 in 2019 The Mazanderani number between three and four million (2006 estimate). Their dominant religion is Shiite Islam. Mazandarani people have a background in Tabari ethnicity and speak tabari  language. Their origin goes back to Tapuri people. So their land was called Tapuria or Tapurestan, the land of Tapuris. Most Mazanderanis live on the southeastern coast of the Caspian Sea. Their traditional professions are farming and fishing. The Mazanderanis are closely related to the neighbouring Gilaki people as well as South Caucasian peoples (e.g., the Georgians, Armenians, and Azerbaijanis). Language. The Mazanderani language is a Northwestern Iranian language spoken by the Mazanderani people; however, most Mazanderanis are also fluent in Persian. The Gilaki and Mazanderani languages (but not other Iranian languages) share certain typological features with Caucasian languages. With  the growth of education and the media, the distinction between Mazanderani and other Iranian languages is likely to disappear. Mazanderani is closely related to Gilaki and the two languages have similar vocabularies. They preserve more of the noun declension system characteristic of older Iranian languages than Persian does. Assistant professor Maryam Borjian of Rutgers University states that Mazanderani has different sub-dialects and there is high mutual intelligibility among Mazanderani sub-dialects. Genetics. The Mazanderani and the closely related Gilaks occupy the south Caspian region of Iran and speak languages belonging to the North-Western branch of Iranian languages. It  has been suggested that their ancestors came from the Caucasus region, perhaps displacing an earlier group in the South Caspian. Linguistic evidence supports this scenario, in that the Gilaki and Mazanderani languages (but not other Iranian languages) share certain typological features with Caucasian languages. Based on mtDNA HV1 sequences, the Gilaki and Mazanderani most closely resemble their geographic and linguistic neighbors, namely other Iranian groups. However, their Y chromosome types most closely resemble those found in groups from the South Caucasus. Researchers have interpreted these differences as demonstrating that males from the Caucasus settled in the south Caspian area and  mated with women from local Iranian groups, possibly because of patrilocality. The Mazanderani and Gilaki groups are closely related on the male side with populations from the South Caucasus such as Georgians, Armenians, and Azerbaijani's. Haplogroups. Analysis of their NRY patrilines has revealed haplogroup J2, associated with the neolithic diffusion of agriculturalists from the Near East, to be the predominant Y-DNA lineage among the Mazanderani (subclades J2a3h-M530, J2a3b-M67 and J2a-M410, more specifically.). The next most frequently occurring lineage, R1a1a, believed to have been associated with early Iranian expansion into Central/Southern Eurasia and currently ubiquitous  in that area, is found in almost 25%. This haplogroup, with the aforementioned J2, accounts for over 50% of the entire sample. Haplogroup G2a3b, attaining significant frequency together with G2a and G1, is the most commonly carried marker in the G group among Mazanderani men. The lineages E1b1b1a1a-M34 and C5-M356 comprise the remainder, of less than 10% sampled. Assimilated populations in Mazandaran. In the Safavid, Afsharid, and Qajar eras Mazandaran was settled by large numbers of Georgians, Circassians, Armenians and other peoples of the Caucasus, whose descendants still live across Mazandaran. The names of many towns, villages and  neighbourhoods in Mazandaran reflect this legacy by bearing variations of the name "Gorji" (i.e., Georgian), although most of the Georgians are assimilated into the mainstream Mazanderanis: they keep a Georgian conscience. The history of Georgian settlement is described by Iskandar Beg Munshi, the author of the 17th century "History of Alam Aray Abbasi". In addition, European travelers such as Chardin and Della Valle have written about their encounters with the Georgian, Circassian and Armenian Mazanderanis.
