War in Donbas

In 2014 Shchastia was controlled by the separatist Luhansk People's Republic from late April 2014 till the Ukrainian Army retook the city on 14 June 2014.^[3] It was mainly retaken by the volunteer fighters of the Aidar Battalion who, according to Amnesty International, then with “virtually no oversight or control” committed acts of violent abuse towards civilians in Shchastia and nearby cities, as did the separatist forces.^[4] According to Shchastia residents this behaviour continued until Aidar was incorporated into the Ukrainian Army in spring 2015.^[4]

On 5 August 2014, a monument of Vladimir Lenin was removed from the city of Shchastia.

To facilitate the governance of Luhansk Oblast during the war in Donbas, the Verkhovna Rada on 7 October 2014 made some changes in the administrative divisions, so that the localities in the government-controlled areas were grouped into districts. In particular, Shchastia was transferred from Luhansk Municipality to Novoaidar Raion.^{[citation needed]}

In July 2020, as part of the reform of administrative divisions in Ukraine, Novoaidar Raion was absorbed into the newly created Shchastia Raion. Shchastia was made the administrative center of the new raion, although Novoaidar served as the de facto administrative center because it was located farther from the line of contact in the Donbas War. By 2022, the town's population had halved to 7,000 in comparison to pre-war numbers.^[5]

Full-scale Russian invasion of Ukraine

In the days before the invasion, the town was shelled and fired upon by Russian-backed forces more than 900 times with incoming munitions from tanks, artillery, mortars, rocket-propelled grenades and small arms. The strikes mostly targeted Ukrainian military installations on the outskirts of Shchastia and the Luhansk Power Plant, damaging buildings, water and electrical lines.^[5]

On February 24, 2022, the first day of the 2022 Russian invasion of Ukraine, Shchastia came under attack by Russian forces and was quickly occupied.^[6] On the second day of the war, the governor Serhiy Haidai said that 80% of the town has been destroyed in the invasion.^[7] According to locals 90% of all houses were destroyed by shelling.^[8]
