Title: Paul I of Russia
Content:  Paul I (Па́вел I Петро́вич Pavel I Petrovich; 1 October 1754 – 23 March 1801) was Emperor of Russia from 1796 until his assassination. Officially, he was the only son of Peter III and Catherine the Great, although Catherine hinted that he was fathered by her lover Sergei Saltykov. Paul remained overshadowed by his mother for most of his life. He adopted the laws of succession to the Russian throne—rules that lasted until the end of the Romanov dynasty and of the Russian Empire. He also intervened in the French Revolutionary Wars and, toward the end of his reign, added Kartli and Kakheti in Eastern Georgia into the empire, which was confirmed by his son and successor Alexander I. He was de facto Grand Master of the Order of Hospitallers from 1799 to 1801 and ordered the construction of a number of Maltese thrones. Paul's pro-German sentiments and unpredictable behavior made him unpopular among Russian nobility, and he was secretly assassinated by his own officers.
Title: Paul I of Russia
Content:  Paul was born in the Palace of Elizabeth of Russia, Saint Petersburg. His father, the future Emperor Peter III, was the nephew and heir apparent of the Empress. The last edition of Catherine's memoirs explained that Peter III was certainly Paul's father after all and why. She lied when hints about another father were written in the first edition, published by Hertzen. His mother, born the daughter of a minor German prince, would later depose her own husband (Paul's father) and reign in her own right as Catherine II, known to history as Catherine the Great. Paul was taken almost immediately after birth from his mother by the Empress Elizabeth, whose overwhelming attention may have done him more harm than good. Once Catherine had done her duty in providing an heir 
Title: Personality and reputation of Paul I of Russia
Content:  Paul I of Russia was Emperor of all the Russias between 1796 and 1801, when he was deposed and assassinated in a palace coup. During his lifetime contemporaries, both at home and abroad speculated as to his mental health, and modern historians have continued to do so. Paul succeeded to the throne on the death of his mother, Catherine the Great, and almost immediately launched a campaign to revoke her legacy. Paul appears to have borne a great hatred for his mother and her acts as Empress, on account of both his upbringing—a lonely one spent mostly away from court—and the fact that Paul held her responsible for the overthrow 
Title: Grand Duke Paul Alexandrovich of Russia
Content:  Grand Duke Paul Alexandrovich of Russia (Павел Александрович; 3 October 1860 – 28 January 1919) was the sixth son and youngest child of Emperor Alexander II of Russia by his first wife, Empress Maria Alexandrovna. He was a brother of Emperor Alexander III and uncle of Nicholas II, Russia's last monarch.

In 1889, he married Princess Alexandra of Greece, his paternal first cousin once removed. The couple had a daughter and a son, but Alexandra died after the birth of their second child. In his widowhood, Grand Duke Paul began a relationship with 
Title: Paul I of Russia
Content:  Emperor Paul was idealistic and capable of great generosity, but he was also mercurial and capable of vindictiveness. In spite of doubts of his legitimacy, he greatly resembled his father, Peter III, and other Romanovs as well and shared the same character. During the first year of his reign, Paul emphatically reversed many of his mother's policies. Although he accused many of Jacobinism, he allowed Catherine's best known critic, Radishchev, to return from Siberian exile. Besides Radishchev, he liberated Novikov from Schlüsselburg fortress, and also Tadeusz Kościuszko, yet after liberation both were confined to their own estates under police supervision. He viewed the Russian nobility as

In 1772, her son and heir, Paul, turned eighteen. Paul and his adviser, Panin, believed he was the rightful tsar of Russia, as the only son of Peter III. His adviser had also taught him that the rule of women endangered good leadership, which was why he was so interested in gaining the throne. Distracting him, Catherine took trouble to find Paul a wife among the minor princesses of the Holy Roman Empire. She chose Princess Wilhelmina of Hesse-Darmstadt, who acquired the Russian name "Natalia Alexeievna", a daughter of

She gave birth to a son, Vladimir, in January 1897, and Eric von Pistohlkors asked for a divorce. Paul wanted to recognize Vladimir as his son and marry Olga, but his family opposed his union. His nephew Nicholas II of Russia and older brother Grand Duke Vladimir Alexandrovich of Russia were particularly angry about his intentions. His brother Grand Duke Sergei Alexandrovich of Russia and his sister-in-law, Grand Duchess Elizabeth begged him to reconsider and think about his

Paul's successor on the Russian throne, his 23-year-old son Alexander, was actually in the palace at the time of the killing; he had "given his consent to the overthrow of Paul, but had not supposed that this would be carried out by means of assassination". General Nikolay Zubov announced his accession to the heir, accompanied by the admonition, "Time to grow up! Go and rule!" Alexander I did not punish the assassins, and the court physician, James Wylie, declared apoplexy the official cause of death.
