Historically, the area of modern-day Tashir was included in the Tashir canton of the historic Gugark province, the 13th province of Greater Armenia.
During the reign of the Arsacid dynasty (52-428 AD) and later under Sasanid Persia (428-651), the area of Artik was ruled by the Kamsarakan Armenian noble family.
With the Arab invasion of Armenia in 654, the region was granted to the Bagratid dynasty, who founded the Bagratid Kingdom of Armenia later in 885.

Between 979 and 1118, the region of Tashir became part of the Kingdom of Tashir-Dzoraget under the rule the Kiurikian dynasty.
Between 1201 and 1360, it was part of Zakarid Armenia under the protectorate of the Kingdom of Georgia.
The region became a prominent centre of the Armenian culture and scholars under the rule of the Zakarid princes of Armenia.
However, after the Mongols captured Ani in 1236, Zakarid Armenia turned into a Mongol protectorate as part of the Ilkhanate.
After the fall of the Ilkhanate in the mid-14th century, the Zakarid princes controlled over Tashir until 1360 when they fell to the invading Turkic tribes.

After suffering from the invasion of Aq Qoyunlu, Kara Koyunlu, Ottomans and Persians from the 14th to 18th centuries, most of the territories in northern Armenia were annexed from Qajar Persia in favour of the Russian Empire In 1801.
The region of Tashir became officially part of the Russian Empire at the Treaty of Gulistan signed on 24 October 1813 between Imperial Russia and Qajar Persia.

Tashir was founded as Vorontsovka in 1844 within the Russian Empire, by Russian migrants who arrived in the area from the region of Saratov.
The newly-established settlement was named after the Viceroy of the Caucasus Mikhail Semyonovich Vorontsov.
In 1846, it was included in the Borchali uyezd of Tiflis Governorate.

In 1935, during the Soviet rule, the settlement was renamed Kalinino after the Russian Bolshevik revolutionary leader Mikhail Kalinin and was called.
