[3] The Barda-Erevan-Nakhchivan-Julfa-Tabriz section of the Great Silk Way linking Azerbaijan's north with Middle Eastern countries passed through Sadarak.

During the 1722 attack of Peter the Great on the Caucasus, including Azerbaijan, Nakhchivan fell under the influence of the Ottomans, while following the 1828 Turkmenchay agreement it was passed on to Russia to become part of Erevan province.

31 December 1989 saw an extraordinary event in USSR history as state borders called "the metal grating" were knocked down enabling people to cross the Aras.

Proceeding from the Kars agreement, the autonomous republic's legislature asked Turkey, Iran, the UN and other international organizations for help.

On 19–20 January 1990, during the First Nagorno-Karabakh War, local Armenian forces seized Sadarak's Karki village.

There are remains of the Sadarak fortress 955 meters above sea level, three medieval mosques, ruins of defence structures, a caravansary, the Agoglan shrine, and a 19-20th century bath-house here.

An important archaeological site in the district of Sadarak is an ancient settlement of Chalcolithic period that stretches over five acres.

[4] It is known as Kultepe Sadarak, and is of remarkable importance because of its multiple cultural layers that go back to the late Paleolithic period.

The settlement is a testimony of local culture in the V millennium BC, and it brings in new information about the Paleolithic Period in Nakhchivan.
