The Constitutional Democratic Party was formed in Moscow on 12–18 October 1905 at the height of the Russian Revolution of 1905 when Tsar Nicholas II was forced to sign the October Manifesto granting basic civil liberties. The Kadets were to the immediate left of the Octobrists, another new formed party organized at the same time. Unlike the Octobrists, who were committed to constitutional monarchy from the start, the Kadets were at first ambiguous on the subject, demanding universal suffrage (including women's suffrage) and a Constituent Assembly that would determine the country's form of government. This radicalism was despite the fact 60% of Kadets were nobles. The Kadets were one of the parties invited by the reform-minded Prime Minister Sergei Witte to join his cabinet in October–November 1905, but the negotiations broke down over the Kadets' radical demands and Witte's refusal to drop notorious reactionaries like Petr Nikolayevich Durnovo from the cabinet.
