[7] On 26 July 2014, he became the speaker of the Parliament of Novorossiya, a confederation that included the separatist Donetsk and Luhansk People's Republics, and served until its dissolution on 18 May 2015.

[2] Tsaryov started his career in 1992 as an engineer for the preparation of production at "Avteks" (Автекс), a specialized small business in Dnipropetrovsk.

[11][2] In the 2012 Ukrainian parliamentary election Tsaryov was re-elected to parliament for Party of Regions again in single mandate district number 40.

According to one source quoted by the National Press Agency of Ukraine, Tsaryov also assured separatists in Donetsk that would do everything to disrupt the May 25, 2014 presidential elections.

The beating was denied by some,[18] though press agencies published videos of the mob and photos of Oleg Tsaryov half-naked with bruises.

[18][21] He added that if they did not withdrew they would be "playing into the hands of the illegitimate authorities and legitimizing not only them but also their decision to start a civil war against the eastern regions".

[8] In May 2014, a recording of a death threat phone call allegedly made to Tsaryov by the governor of Dnipropetrovsk Oblast and owner of PrivatBank, Ihor Kolomoyskyi, began circulating in social media.

In the call, Kolomoyskyi told Tsaryov that there was a bounty of $1 million on his head, and to stay in Moscow if he did not want to be killed.

[citation needed] On 3 June 2014 Tsaryov was stripped of his parliamentary immunity by the Verkhovna Rada (Ukraine's parliament) who also sanctioned his arrest.

[8] Tsaryov is now wanted for making "public calls to overthrow the existing constitutional system in Ukraine, change its state borders and stage acts of disobedience, which entailed grave consequences and caused many casualties among law enforcers and peaceful civilians".

[26] The United States intelligence community named Tsaryov as a possible Kremlin supported choice to lead a pro-Russian puppet Ukrainian government.

[33] After the visit of Boris Johnson to Kyiv on April 10, Tsaryov suggested shooting down airplanes with foreign politicians.

Vladimir Rogov, a pro-Russian politician in occupied Ukraine, claimed a day later that Tsaryov was transferred to a hospital in a "very serious" condition.

[45] In November 2013 Tsariov demanded a criminal investigation into the activities of United States Department of State lead TechCamp in Ukraine because he believed it was engaged in "preparations for inciting a civil war" because during training "instructors share their experience of Internet technologies, which are aimed at shaping public opinion and enhancing the protest potential and which were used to organize street protests in Libya, Egypt, Tunisia and Syria".

Among those named in the document notably included Andreas Umland, Stanislav Belkovsky, Taras Kuzio, Gleb Pavlovsky, and former Georgian president Mikheil Saakashvili, among others.
