As the Crimean crisis unfolded, the Parliament building was seized by unidentified pro-Russian gunmen. Under their control, the Parliament removed the incumbent Ukrainian-consented Prime Minister of Crimea and unilaterally appointed Sergey Aksyonov in his stead. The disbandment was also caused by the belief that the Crimean Parliament collaborated with Russian troops in the region against Ukrainian authorities. Days later, the Crimean Parliament reunified its territorial jurisdiction with the city of Sevastopol into a single united nation and unilaterally declared their independence from Ukraine following a referendum that reflected such desire. This newly formed nation then acceded to Russia which ultimately transferred the Crimean Parliament under a newly formed federal subject of Russia.
