Unfortunately, Azerbaijan existed long before 1918. Below is the excerpt from the British Royal Geography Society book of 1864. The country known to the Persians as Azerbaijan is divided between them and Russia, the latter Power possessing about five-eighths of the whole, which may be roughly stated to cover an area of about 80,000 square miles, or about the size of Great Britain ; 50,000 square miles are therefore about the extent of the division belonging to Russia, and 30,000 of that which remains to Persia. The Russian division is bounded on the north and north-east by the mountains of Caucasus, extending to the vicinity of Bakou on the Caspian. On the west it has the provinces of Imeritia, Mingrelia, Gooriel, and Ahkhiska (now belonging to Russia) ; on the east it has the Caspian Sea, and on the south the boundary is marked by the course of the River Arrass (Araxes) to near the 46th parallel of longitude, thence by a conventional line across the plains of Moghan to the district of Talish, and by the small stream of Astura which flows to the Caspian through the latter country. In this area are contained the following territorial divisions : — Georgia or Gurjistan, comprising Kakhetty, Kartaliny, Somekhetty, Kasakh ; the Mohammedan countries of Eriwan, Nakhshewan, Karabagh, Ghenja, Shir wan, Shekky, Shamachy, Bakou, Koobeh, Salian and a portion of Titlish https://archive.org/details/jstor-1799149/page/n1/mode/2up

What a disgusting/disgraceful coward (and unfortunately, a half-Armenian) Lavrov-Kalantaryan is! As a so-called "top diplomat" he is well aware of the historical fact that Artsakh had never been part of Azerbaijan simply because it has a history of 1000s of years. In contrast, Azerbaijan has been in existence since 1918. Artsakh was an integral part of the historic Armenian Kingdom (the tenth province of Armenia from 189 BC until 387 AD), and part of the Eastern Armenian Kingdom, both under the Persian and Arab rule as a part of the Armenian administrative unit, until beginning of 19th century when it was annexed to Russian empire as a result of Russian-Persian war. Along with Nakhichevan, it was annexed to newly created state of Soviet Azerbaijan in 1921 by decree of despot Stalin in an effort to placate the oil-producing Azerbaijan and Bolshevik Russia’s Kemalist allies in Turkey. Therefore, annexation of Artsakh to the newly created Soviet Azerbaijan was a generous gift to them by despot Stalin. In this regard the hypocrisy of the so-called "WESTERN CIVILIZED WORLD" is really disgusting. When it comes to anti-communism propaganda, then Stalin is called an "evil dictator" (which is very true)! However, when it comes to the “territorial integrity of Azerbaijan”, the decree of the same "evil dictator" (i.e. donating Artsakh and Nakhichevan to Azerbaijan) becomes "international law"! What a disgusting hypocrisy, eh?

Which azerbaijan are you talking about Mr Lavrov Kalantaryan? The fake azerbaijani state established by criminals (who now want to reset the whole planet) to steal oil resources from the ancestral territory of Armenia? Azerbaijan is a fake country https://sites.google.com/site/azerbaijanisafakecountry/
