Historically, the area of modern-day Tumanyan was included in the Dzorapor () canton of the historic
Gugark province, the 13th province of
Greater Armenia. Prior to the foundation of the
Republic of Armenia in 1918, the area was part of the
Borchali uyezd of
Tiflis Governorate, within the
Russian Empire. In late 1918,
Armenia and
Georgia fought a
border war over the region of Lori. In January 1919, the Lori neutral zone was established by the British forces. Following Armenia's Sovietization in December 1920, Lori was finally incorporated into
Soviet Armenia on 11 February 1921. In 1926, the village of
Dzaghidzor was founded on the right bank of
Debed river. In 1930, it was included within the newly founded
Tumanyan raion. In 1934,
refractory metals mines were found north of Dzaghidzor village. The production of fireproof materials extracted from the mines of Dzaghidzor was launched in 1939. With the rapid growth of the village, Dzaghidzor was granted the status of an
urban-type settlement in 1947 and it was about this time when architect Sos Manukyan designed the modern layout of the central part of Tumanyan, with a town square, parks, school, house of culture and other public spaces. In 1951, the settlement was renamed
Tumanyan. During the 1950s, the Kober railway station was opened on the left bank of Debed river, around northwest of Tumanyan, to serve the Tumanyan fireproof materials factory opened in 1951. In 1995, the government of independent Armenia reaffirmed the status of Tumanyan as an urban settlement within the
Lori Province. Besides the town of Tumanyan, the nearby villages of
Atan,
Shamut,
Karinj,
Lorut,
Marts,
Kober kayaran and
Ahnidzor are also under the jurisdiction of the municipality of Tumanyan. == Geography ==
