Bolsheviks formed part of the Red Army. They started a provisional government that led to the formation of communism and the Soviet Union in Russia. This group represents the end for the Russian Empire, and henceforth they controled the Russian Revolution.
Their role during the Russian Revolution was related to the Romanov Royal Family. Tsar Nicholas II possessed the title of Russian Emperor at that time, he was assassinated with his entire family by the Bolsheviks in 1917. This monarch had rather incompetent counselors, they aimed the tsar to kill people unfairly and stop attending their major problems- such as hungry.

Miranda v. Arizona was a case decided by the Warren court on June 13, 1966. Ernesto Miranda had a written confession for kidnap and r*pe, but the issue was that police interrogated him without the presence of a lawyer, neither the police officers told him he had the right to call a lawyer.
The Court's decision favored Miranda, overturned his conviction and the case was sent to Arizona for retrial.
