Russian Empire
Though the Empire was only officially proclaimed by Tsar Peter I following the Treaty of Nystad (1721), some historians would argue that it was truly born either when Ivan III of Russia conquered Veliky Novgorod in 1478, or when Ivan the Terrible conquered the Khanate of Kazan in 1552. According to another point of view, the term "Tsardom", which was used after the coronation of Ivan IV in 1547, was already a contemporary Russian word for empire.
Russo-Persian War (1804–13)
The origins of the first full scale Russo-Persian War can be traced back to the decision of Tsar Paul to annex Georgia (December 1800) after Erekle II, who had been appointed as ruler of Kartli several years earlier by his ruler Nader Shah, made a plea to Christian Russia in the Treaty of Georgievsk of 1783 to be incorporated into the empire. After Paul's assassination (11 March 1801), the activist policy was continued by his successor, Tsar Alexander, aimed at establishing Russian control over the khanates of the eastern Caucasus. In 1803, the newly appointed commander of Russian forces in the Caucasus, Paul Tsitsianov, attacked Ganja and captured its citadel on 15 January 1804. Ganja's governor, Javad Khan Qajar, was killed, and a large number of the inhabitants slaughtered. The Qajar ruler, Fath Ali Shah, saw the Russian threat to Armenia, Karabagh, and Azerbaijan not only as a source of instability on his northwestern frontier but as a direct challenge to Qajar authority.
