Gadili is a village in the Iravan uezd of the former Iravan governorate, later in the former Vedi district, and currently in the Ararat province. The provincial centre lies 43 km to the southeast of the town of Gamarli (Artashat), at the foot of Varsag Mountain, on the banks of the Chapan River, at a height of 2,000 m above sea level. It was marked as “Gadli” in “The Iravan Province Comprehensive Data Book” compiled in 1590 and as “Gadilu” on the five-verst map of the Caucasus. In their works Armenian authors also marked the name of the village as “Gadirli”. In “The Iravan Province Comprehensive Data Book” compiled in 1590, it was marked as “Gadli village” on the list of settlements within the Vedi area. Although the historical name of the village is “Gadili”, it was formalized as “Gadirli” during the Soviet period.

The village was inhabited by 45 Azerbaijanis in 1831, 389 in 1873, 497 in 1886, 588 in 1897, 827 in 1904, 839 in 1914 and 697 Azerbaijanis in 1916. In 1919 the Azerbaijanis were expelled as a result of massacres committed by Armenian armed forces. Beginning from 1926 only Armenians started to live in the village.

The toponym was formed on the basis of the name of the Turkic Gadili tribe. The Gadili tribe was one of the branches of the Gashgais.

By the decree of the Presidium of the Supreme Soviet of the Armenian SSR dated 3 July 1968, the village was renamed “Lanjanist”. According to the law “On the administrative-territorial division of the Republic of Armenia” dated 7 November 1995, it was integrated into the administrative area of the Ararat province.
