11. During Nicholas reign, the House of Romanov faced a series of calamities. The eccentric Russian monk Rasputin gained power and influence, leading to controversy. Russias defeat in the Russo-Japanese War further undermined Nicholas rule. Additionally, the 1905 Revolution resulted in the establishment of the Duma, Russias first democratic body. The downfall of Nicholas and his government came swiftly during the February and October Revolutions of 1917. A small group of Communists, led by Vladimir Lenin and Leon Trotsky, overthrew the czar. Less than a year later, amidst the Russian Civil War, the entire imperial family, including Nicholas 13-year-old son and potential heir, was brutally assassinated in Yekaterinburg. This tragic event marked the definitive and bloody end of the Romanov dynasty.
