query: Who started the Russian empire?
passage: 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.
passage: Russian wine
The founder of modern commercial wine-making in Russia was Prince Leo Galitzine (1845-1915), who established the first Russian factory of champagne wines at his Crimean estate of Novyi Svet. In 1889 the production of this winery won the Gold Medal at the Paris exhibition in the nomination for sparkling wines, although several years previously the wine regions of Russia had been devastated by the Phylloxera epidemic. In 1891, Galitzine congratulated himself on becoming the surveyor of imperial vineyards at Abrau-Dyurso, where the sparkling wine was produced throughout the 20th century under the brand of Soviet Champagne, or "champagne for the people".
