In 1862, Lori was transferred into the jurisdiction of the Tiflis Governorate. In 1880, Lori became part of the Borchali uyezd of the Tiflis Governorate. In the early 20th century, Lori was mostly populated by Armenians, with several Russian and Greek villages. In May 1918, the Ottoman Turkish forces moved towards Yerevan and Karakilisa (now Vanadzor). On 25 May 1918, the Armenians led by Garegin Nzhdeh fought against the Turkish forces led by Wehib Pasha, at the vicinity of Karakilisa. On 28 May 1918, the Turks retreated from Karakalisa, Abaran and Sardarabad, paving way towards the declaration of the Republic of Armenia on the same day.
