History of Russia
The war ended in 1721 when an exhausted Sweden sued for peace with Russia. Peter acquired four provinces situated south and east of the Gulf of Finland, thus securing his coveted access to the sea. There, in 1703, he had already founded the city that was to become Russia's new capital, Saint Petersburg, as a "window opened upon Europe" to replace Moscow, long Russia's cultural center. Russian intervention in the Commonwealth marked, with the Silent Sejm, the beginning of a 200-year domination of that region by the Russian Empire. In celebration of his conquests, Peter assumed the title of emperor, and the Russian Tsardom officially became the Russian Empire in 1721.
Russian Empire
The Russian Empire was, predominantly, a rural society spread over vast spaces. In 1913, 80% of the people were peasants. Soviet historiography proclaimed that the Russian Empire of the 19th century was characterized by systemic crisis, which impoverished the workers and peasants and culminated in the revolutions of the early 20th century. Recent research by Russian scholars disputes this interpretation. Mironov assesses the effects of the reforms of latter 19th-century especially in terms of the 1861 emancipation of the serfs, agricultural output trends, various standard of living indicators, and taxation of peasants. He argues that they brought about measurable improvements in social welfare. More generally, he finds that the well-being of the Russian people declined during most of the 18th century, but increased slowly from the end of the 18th century to 1914.
