The Kadets' position in the Provisional Government was compromised when Miliukov's promise to the Entente allies to continue the war (18 April) was made public on 26 April 26. The resulting government crisis led to Miliukov's resignation and a powersharing agreement with moderate socialist parties on 4–5 May. The Kadets' position was further eroded during the July crisis when they resigned from the government in protest against concessions to the Ukrainian independence movement. The coalition was reformed later in July under Alexander Kerensky and survived yet another government crisis in early September. Sergei Fedorovich Oldenburg was Minister of Education and served briefly as chair of the short-lived Commission on Nationality Affairs. The Kadets had become a liability for their socialist coalition partners and an evidence of the treason of the moderated socialists, exposed by Bolshevik propaganda. With the Bolshevik seizure of power on 25–26 October and subsequent transfer of political power to the soviets, Kadet and other anti-Bolshevik newspapers were closed down and the party was suppressed by the new regime.
