Language and region are fault lines in Ukraine's conflict

Ukraine's east and south—largely Russian-speaking—differ from the Ukrainian-speaking west and center. These geographic, linguistic, and cultural divides have become fault lines exploited by political and military conflict since 2014.

Russia's full-scale invasion of Ukraine began on Feb. 24, 2022

Russia launched a massive multifront assault from Belarus, Russia, and Crimea, aiming to seize Kyiv within days. Instead, Ukrainian forces repelled the advance, halting Moscow's plans for a rapid takeover.

Russia controls about 20% of Ukraine's territory

As of February 2026, Russian forces occupy roughly one-fifth of Ukraine, including Crimea and large parts of the Donetsk, Luhansk, Zaporizhzhia, and Kherson regions, with front lines largely unchanged for months.

Protests in Ukraine from 2013 to 2014 set the stage for the current conflict

Beginning in November 2013, the Euromaidan movement saw hundreds of thousands of protesters gather in Kyiv's Independence Square after the government rejected an EU deal. Months of demonstrations and violent crackdowns culminated in President Yanukovych fleeing to Russia. Note: graphic content.

The origins of Ukrainian identity are a matter of historical debate

Scholars disagree on when a distinct Ukrainian identity emerged. Some trace it to Kyivan Rus, a medieval East Slavic state centered in Kyiv, while others argue that Ukrainian nationhood developed much later, shaped by centuries of foreign rule and cultural revival movements.

Kyivan Rus laid the cultural foundations for Eastern Europe

From the 9th to the 13th centuries, Kyivan Rus was a powerful East Slavic state centered in Kyiv. It shaped the region's language, religion, and political traditions—forming the shared cultural roots of modern-day Ukraine, Russia, and Belarus.

Ukraine came under Russian imperial rule in the late 18th century

After centuries of division among neighboring powers, most of present-day Ukraine was absorbed into the Russian Empire by the late 1700s, marking the beginning of a long period of imperial control and cultural suppression.

Ukrainian nationalism rose under imperial repression

In the 19th century, Ukrainian nationalism took shape through cultural revival movements and intellectual circles—even as the Russian Empire banned the Ukrainian language and sought to suppress Ukrainian identity.
