Kirill Stremousov

Following the 2022 Russian invasion of Ukraine and the occupation of Kherson Oblast, Stremousov took a pro-Russian position. On 16 March 2022, Stremousov and other local pro-Russian activists held a meeting of the collaborationist Salvation Committee for Peace and Order in the building of the Kherson Regional Administration. The following day, the Ukrainian government accused Stremousov of treason for his role in this meeting and opened criminal proceedings against him.

On 26 April 2022, Stremousov was appointed by the Kremlin the deputy governor of the Kherson Military-Civilian Administration. Analysing this choice, The Guardian later said that "with much of the Kherson Ukrainian administration gone or refusing to serve the Russians, Moscow turned to figures such as Stremousov to try to give an appearance of legitimacy to their occupation."

In an indication of an intended split from Ukraine, Stremousov announced two days later that the region would switch its currency to the Russian ruble the following month. Additionally, citing unnamed reports that alleged discrimination against Russian speakers, Stremousov said that "reintegrating the Kherson region back into a Nazi Ukraine is out of the question". On 11 May 2022, Stremousov announced his readiness to turn to President Vladimir Putin with a request for Kherson Oblast to join the Russian Federation, noting that there would be no creation of the "Kherson People's Republic" or referendums regarding this matter. After this announcement, leaflets started appearing around Kherson offering a ₴500,000 reward for Stremousov's assassination.

On 3 June 2022, Stremousov was sanctioned by the European Union for providing support and promoting policies that undermine the territorial integrity, sovereignty and independence of Ukraine.

Analysis of a video made by Stremousov during the Ukrainian counter-attack on Kherson started on 29 August 2022 shows landmarks in the background that identify the location as the Marriott Hotel at 38 Revolyutsii Avenue, Voronezh, a city in southwestern Russia 550 miles (890 km) from Kherson. This is interpreted as being due to his having fled. When asked about his location, Stremousov said he was "travelling around Russian cities, meeting different people for work".

On 9 November 2022, Stremousov died in a car crash near Henichesk, Russia's de facto headquarters in the region, at the age of 45. His death came hours prior to Russia's official retreat from Kherson city. President Vladimir Putin posthumously awarded Stremousov the Order of Courage. Stremousov was buried on 11 November in Simferopol. The Russia-backed administration of the Kherson Oblast promised to name a street after Stremousov in the city of Kherson and erect a statue to commemorate his life. In a post on the Telegram messaging app, Sergey Aksyonov, head of the Russia-annexed Crimea Peninsula, called Stremousov a “true fighter” and a “Russian patriot”. Stremousov's funeral was attended by First Deputy Chief of Staff of the Presidential Administration of Russia Sergey Kiriyenko.

Stremousov became a member of the pro-Russian Derzhava party in 2021.

During the COVID-19 pandemic, Stremousov started promoting anti-vaccination beliefs and conspiracy theories. In his videos he accused the authorities of spreading COVID-19, spoke about "US biolabs in Ukraine", and urged residents not to wear masks and not to adhere to restrictions. On 18 June 2020, he attacked journalist Dmytro Bagnenko and was involved in a criminal case under the article on obstruction of the journalist's work. In August 2020, the SBU conducted searches of Stremousov's properties as part of criminal proceedings to expose the Russian FSB.

In the 2020 local elections he unsuccessfully ran for the post of mayor of Kherson as a self-nominated candidate, receiving just over 1% of the vote.

On 18 January 2019, he was part of a group that fired at the Novy Den newspaper in Kherson. For this he was suspected of hooliganism.

In January 2019, he was expelled from the Socialist Party of Ukraine. In the 2019 Ukrainian parliamentary election he was a candidate for the People's Deputy of Ukraine as a self-nominated candidate in the 82nd constituency, receiving 1.74% of the vote.

In January 2016, he co-founded the Ukrainian Center for Environmental Self-Defense. In February 2017, he beat a police officer during a fight in the city council. On 21 May 2018, Stremousov shot a man with a traumatic pistol [uk] (a non-lethal weapon) in the Henichesk district. On 6 April he was involved in the attack on the SBU convoy.

On 8 October 2018, he was named the head of the Kherson branch of the Socialist Party of Ukraine.

In late 2017, Stremousov faced backlash and coverage from international tabloids after he filmed himself spinning his four months old daughter around his head by her legs. While doing this, he said that he could hear “her bones are popping.” The newspaper The Financial Express called Stremousov "heartless" and emphasized that he ignored the screams of the baby.

In 2013, Stremousov was one of the organizers of the "Russian runs", which were to show Kherson the "strength of the Russian spirit". In December 2013, he founded the organization "For the President", which provided explicit support to the pro-Russian President Viktor Yanukovych.
