Nicholas I of Russia
Early life and road to power

Nicholas was born at Gatchina Palace in Gatchina, the ninth child of Grand Duke Paul, heir to the Russian throne, and Grand Duchess Maria Feodorovna of Russia (née Sophie Dorothea of Württemberg). He had six older sisters and two older brothers, namely the future Emperor Alexander I of Russia and Grand Duke Constantine Pavlovich of Russia.

Four months after Nicholas's birth, his grandmother, Catherine the Great, died and his parents became Emperor and Empress of Russia. In 1800, at the age of four years, Nicholas was named Grand Prior of Russia and entitled to wear the Maltese cross. Nicholas grew up to be a fine young man. Riasanovsky says of him that he is "the most handsome man in Europe, but also a charmer who enjoyed feminine company and was often at his best with the men."

On 13 July 1817, Nicholas married Princess Charlotte of Prussia (1798–1860), who took the name Alexandra Feodorovna when she converted to Orthodoxy. Charlotte's parents were Frederick William III of Prussia and Louise of Mecklenburg-Strelitz. Nicholas and Charlotte were third cousins, as they were both great-great-grandchildren of Frederick William I of Prussia.

With two older brothers, it initially seemed unlikely Nicholas would ever become Tsar. However, as Alexander and Constantine both failed to produce legitimate sons, Nicholas first came to attention as being likely to rule one day, or at least that his children may succeed. In 1825, when Tsar Alexander died suddenly of typhus, Nicholas was caught between swearing allegiance to Constantine and accepting the throne for himself. The interregnum lasted until Constantine, who was in Warsaw at that time, officially forfeited his right to succession. This had been required by Tsar Alexander as a condition of Constantine's marriage to his second wife Joanna Grudzinska. On 25 (13 Old Style) December, Nicholas issued the manifesto proclaiming his accession to the throne. That manifesto retroactively named 1 December (19 November Old Style), the date of Alexander I's death, as the beginning of his reign. During this confusion, a plot was hatched by some members of the military to overthrow Nicholas and seize power. This led to the Decembrist Revolt on 26 (14 Old Style) December 1825, an uprising Nicholas quickly suppressed.
