Ever since its inception, Russia has been defined both by itself and by its (often short-lived) neighbors as an aggressively expansionist power. Like many other powers, this became the defining feature of Russia, a form of consistency across regimes. Whether it was the ancient Rurikids, expanding 18,000 miles a year under Ivan the Terrible, or the Romanovs expanding into the Ukraine and Alaska, Russian rule was synonymous with expansion.
