NICHOLAS I OF RUSSIA
Different Christian European powers moved in and out of alliances with each other and with the Islamic Ottoman Empire. So Christians were not unified and whenever a Christian country was at war with the Muslims some Christians perceived it as an assault on Christianity—except that there were Christian allies of the Muslims. Later many Muslims would see any conflict with a Christian country as an attack in Islam even when Muslim nations were allied with the Christians as was Turkey at the end of the 20th century. Turkey was a member of NATO and was therefore seen as traitors to Islam by some Muslims. There has always been this tendency to see conflict in terms of religious or ethnic hostility where convenient.
Nicholas I (6 July 1796 – 2 March 1855) was Emperor of Russia, King of Congress Poland, and Grand Duke of Finland. He was the third son of Paul I and younger brother of his predecessor, Alexander I. Nicholas's thirty-year reign began with the failed Decembrist revolt. He is mainly remembered as a reactionary whose controversial reign was marked by geographical expansion, centralisation of administrative policies, and repression of dissent both in Russia and among its neighbors. Nicholas had a happy marriage that produced a large family; with all of their seven children surviving childhood.
