The house arrest was lifted again in November, and the Constituent Assembly was elected and met in January 1918. Despite being the minority party, the Bolsheviks dissolved it. On 3 March 1918 (N.S.), the Bolshevik government signed the Treaty of Brest-Litovsk, which effectively ceded vast areas of the former Russian Empire to the Central Powers of Germany, Austria-Hungary and the Ottoman Empire. On 7 March 1918, Michael and his secretary Johnson were re-arrested on the orders of Moisei Uritsky, the Head of the Petrograd secret police, and imprisoned at the Bolshevik headquarters in the Smolny Institute.
