The Right Sector has gained popularity with the radicalisation of public sentiment at the turn of 2013 and 2014. Primarily during the January 2014 confrontation with Berkut at ul. Hruszewski in Kiev, the organisation that brings together radical nationalists became known.
Following President Viktor Yanukovych's escape in March 2014, the Right Sector political party was established as the political wing of the movement. Russia recognized the organisation as extreme. In March 2014, the Investigative Committee of the Russian Federation launched a case against the leader of the organisation Dmytri Jarosz.
In July 2014, the Right Sector created the Ukrainian Volunteer Corps (DUK), which took part in the fighting in the east of the country, including the Battle of Donetsk Airport. Jarosz himself also fought, although in October 2014 he became deputy of the Verkhovna Rada of Ukraine. In January 2015, he was wounded near Donetsk as a result of the firing of Grad missiles.
On July 11, 2015, members of the Right Sector came with weapons to Mukachevo in the Transcarpathian region. There was an exchange of fire with the police. Several people died.
In November 2015, Dmytro Jarosz resigned from the position of the leader of the Right Sector. The organisation has split.
Most of the members of the Ukrainian Volunteer Corps fighting in Donbass have gone on to serve in the Armed Forces of Ukraine. Yet, still to this day, soldiers originating from the Right Sector have been using the symbolism and signs identifying them with their organisation on the front.
