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.
