Yemelyan Pugachev
Yemelyan Ivanovich Pugachev () (c. 1742 – ) was a Russian Cossack who led a great popular insurrection during the reign of Catherine the Great, claiming to be her late husband, Emperor Peter III. Alexander Pushkin wrote a notable history of the rebellion, "The History of Pugachev", and he recounted some of the events in his novel "The Captain's Daughter" (1836).
Workers' Opposition
The Workers' Opposition was led by Alexander Shlyapnikov, who was also chairman of the Russian Metalworkers' Union, and it consisted of trade union leaders and industrial administrators who had formerly been industrial workers. Alexandra Kollontai, the famous socialist feminist, was the group's mentor and advocate. Other prominent members included Sergei Medvedev and Mikhail Vladimirov (leaders of the Metalworkers' Union), Alexander Tolokontsev and Genrikh Bruno (artilleries industry leaders), Mikhail Chelyshev (a member of the Party Control Commission), Ivan Kutuzov (chairman of the Textileworkers' Union), Kirill Orlov (member of the Council of Military Industry and a participant in the 1905 mutiny on the Russian battleship Potemkin), and Aleksei Kiselyov (chairman of the Miners' Union). Yuri Lutovinov, a leader of the Metalworkers' Union and of the All-Russian Council of Trade Unions, sometimes spoke for the group, but sometimes held his own opinion.
