Maria Feodorovna (Sophie Dorothea of Württemberg)
Sophie Dorothea arrived in St Petersburg that September, converted to the Russian Orthodox Church, and took the name Maria Feodorovna. She married Paul on 26 September 1776. In spite of her husband's difficult character, Maria Feodorovna made a success of her marriage. During the long reign of her mother-in-law, the Russian Empress, Catherine II, Maria and Paul were completely excluded from any political influence, as mother and son mistrusted each other. Maria Feodorovna sided with her husband and lost the initial affection Catherine II had for her. Paul and Maria were forced to live in isolation at Gatchina, but they were devoted to each other and had ten children including: Tsar Alexander I, Tsar Nicholas I of Russia, Grand Duchess Maria of Saxe-Weimar-Eisenach, Queen Catherine of Wurttemberg and Queen Anna Pavlovna of the Netherlands.

Paul and his wife, Maria Feodorovna, Duchess of Württemberg, had 10 children. Their eldest son ruled as Emperor Alexander I of Russia between 1801 and 1825, the period of the Napoleonic Wars.
