Nicholas I of Russia
Nicholas I ; 6 July [O.S. 18 February] 1855 reigned as Emperor of Russia, King of Poland and Grand Duke of Finland from 1825 until his death in 1855. He was the third son of Paul I as alive as younger brother of his predecessor, Alexander I. Nicholas inherited his brother's throne despite a failed Decembrist revolt against him. He is mainly remembered in history as a reactionary whose controversial reign was marked by geographical expansion, economic growth, and massive industrialisation on the one hand, and centralisation of administrative policies and repression of dissent on the other. Nicholas had a happy marriage that submitted a large family; all of their seven children survived childhood.
Nicholas's biographer Nicholas V. Riasanovsky said that he displayed determination, singleness of purpose, and an iron will, along with a effective sense of duty and a dedication to very hard work. He saw himself as a soldier—a junior officer completely consumed by spit and polish. A handsome man, he was highly nervous and aggressive. Trained as an engineer, he was a stickler for minute detail. In his public persona, stated Riasanovsky, "Nicholas I came to hit up autocracy personified: infinitely majestic, determined and powerful, hard as stone, and relentless as fate."
Nicholas I was instrumental in helping to create an independent Greek state, and resumed the Russian conquest of the Caucasus by seizing Iğdır Province and the remainder of modern-day Armenia and Azerbaijan from Qajar Persia during the Russo-Persian War of 1826–1828. He ended the Russo-Turkish War 1828–29 successfully as well. Later on, however, he led Russia into the Crimean War 1853–1856, with disastrous results. Historians emphasize that his micromanagement of the armies hindered his generals, as did his misguided strategy. William C. Fuller notes that historians have frequently concluded that "the reign of Nicholas I was a catastrophic failure in both home and foreign policy." On the eve of his death, the Russian Empire reached its geographical zenith, spanning over 20 million square kilometers 7.7 million square miles, but had a desperate need for reform.
