With a population of just 2.6 million and one of the smallest economies in Europe, Moldova barely registers by most European Union metrics. Yet the small former Soviet republic wedged between EU member Romania and war-ravaged Ukraine has drawn outsized attention from the continent’s powerful democracies and Vladimir Putin’s Russia.

Moldova, the EU and the United States said the Kremlin had waged a "hybrid war" campaign to destabilize the country and keep it in Russia's sphere of influence, including funding pro-Moscow parties, spreading disinformation and pouring millions of dollars into schemes to buy up 300,000 votes. Nearly 1.5 million Moldovans ultimately voted.

The country’s aspiration to join the E.U. will now be enshrined in the constitution but the referendum was incredibly close.
