Eight years ago, the breakaway enclaves of Donetsk and Luhansk, in Ukraine's eastern Donbas region,
became the site of fighting between Russian-backed separatists and Ukrainian forces. That same year, 2014, Russia also annexed Crimea, sparking global condemnation.

Beyond Europe's borders, Russian forces entered Syria's long civil war in 2015, bolstering ally President Bashar al-Assad's regime. In the wake of Russia's massive bombing assault on Aleppo, the country lost its seat
on the United Nations Human Rights Council.
We asked refugees and displaced people from each of these conflicts to share their stories of forging new lives -- and the lessons for Ukraine today. The opinions expressed in these commentaries are their own.
