"Now home to a majority of Russian-speaking people, they moved there only in recent decades. Now, Russia has given more than 720,000 Russian passports to roughly one-fifth of the region’s population, according to The Associated Press."
"In March of 2014, following the Euromaidan and the 2014 Ukrainian revolution, large swaths of the Donbas experienced major unrest. This later grew into a war, with pro-Russian separatists affiliated with the self-proclaimed Donetsk and Luhansk “People’s Republics”"
"Pro-Russian separatists in the Donetsk and Luhansk regions took over government buildings in 2014, proclaiming the regions as independent “people’s republics” after Russia’s annexation of Crimea from Ukraine.
Since 2014, more than 14,000 people have been killed in fighting in the Donbas region between pro-Russian separatists and Ukrainian forces."
"On Monday, Putin announced the independence of the regions after meeting with the Russian Security Council following a video appeal by the regions’ separatist leaders for the recognition of independence.
Each of the regions has its own self-proclaimed president, with Denis Pushilin elected in 2018 to lead the so-called Donetsk People’s Republic, while Leonid Pasechnik is the leader of the Luhansk separatist region.
Russia’s recognition of the independence of the regions on Monday in effect ends the Minsk peace agreements, which were never fully implemented in any case. The agreements, which were signed in 2014 and 2015, had called for a large amount of autonomy for the two regions within Ukraine."
