Annexation of Crimea by the Russian Federation - 2014 -

In 2014, the Euromaidan protests in Kyiv ended with the pro-Russia ex-president of Ukraine Viktor Yanukovych being ousted in the Revolution of Dignity. Shortly afterwards, Russia mobilized its military and sent troops to Ukraine in order to complete the job Yanukovych had failed to finish: reinstating Russian rule in the region of Crimea.

Annexation of Crimea by the Russian Federation - 2014 -

Despite intense public outcry from Ukraine and the West, Russian forces went along with their invasion and declared Crimea a de facto republic of Russia. Tensions between Ukraine and Russia were extremely high for the eight years that followed, and finally boiled over with Russia's "special military operation" in the eastern territories of Ukraine. But these campaigns of invasion in recent years are far from Russia's first foray into imperialism. The nation in various forms over the years has sought to expand its power.

The Russo-Persian Wars raged intermittently for hundreds of years, with the first conflict beginning in 1651 and the last concluding in 1828, with the signing of the Treaty of Turkmenchay.

The Bolshevik Red Army started an offensive campaign to take control of Estonia shortly after German troops left the area in 1917. By the end of 1918, the Russian army was at Estonia's doorstep, and while the infant nation had little chance of defending itself, Western allies provided support.

Occupation of the Baltic states: Estonia - 1940 -

Russo-Georgian War - 2008 -

Considered the first international European war of the 21st century, the Russo-Georgian War was caused by increasingly uneasy tensions between the two formerly-Soviet nations. After Georgia had declared independence from a weakened Soviet Union in 1991, two separatist movements emerged and declared themselves de facto sovereign states.

Russo-Georgian War - 2008 -

Violence broke out in 2008 after South Ossetian separatists fired artillery into Georgian villages on their border, and Georgia promptly asserted control over the Ossetian capital of Tskhinvali. Russia, who had for years backed the Ossetian separatists, proceeded to launch a full-scale invasion into Georgia. Both Russia and South Ossetia have been accused of war crimes during this conflict, including the ethnic cleansing of Georgians.
