Another neighbor to the Lezgin people would be the closely related Aghuls. The Aghul people have a population of about 34,160 and speak the Aghul language which is part of the Lezgi group of languages as well. They are very similar in relations to ethnicity to the Lezgin. They also have a majority of Sunni Muslims.
More neighbors of the Lezgin people are the Tsakhur people. The Tsakhur people have a population of about 45,000 and refer to themselves as yiqi. Their name, Tsakhur, comes from the Dagestani village they live in. Like their neighbors, they too were converted to Islam.
