Like many European countries during the Great Age of Discovery and Exploration, Russia embarked on policies of state building, exploration and imperial expansion. At the beginning of the fourteenth century, the territory under Moscow's control was about 20,000 square kilometres. By 1800 Russia's empire had expanded to some 18 million square kilometres. Russia had thus become one of the world's greatest empires. By focusing on such geographical practices as exploring, observing, describing, mapping and similar activities, Reconnoitring Russia seeks to explain how Russia's rulers and its educated public came to know and understand the territory of their expanding state and empire, especially as a result of the modernizing policies of such sovereigns as Peter the Great and Catherine the Great. It places the Russian experience into a comparative context, showing how that experience compares with those of other European countries over the same period. The book adopts a broad chronological framework, exploring the age between 1613 when the Romanov dynasty assumed power and 1825, the conclusion of Alexander I's reign, or what is often termed the end of the 'long eighteenth century'.
