Paul I of Russia
Paul I (; "Pavel Petrovich") ( – ) reigned as Emperor of Russia between 1796 and 1801. Officially, he was the only son of Peter III and Catherine the Great, though Catherine hinted that he was fathered by her lover Sergei Saltykov, who also had Romanov blood, being a descendant of the first Romanov tsar's sister, Tatiana Feodorovna Romanova.
Yugoslav regency
On 9 October 1934 IMRO member Vlado Chernozemski assassinated King Alexander I of Yugoslavia in Marseille in France, and Alexander's cousin Prince Paul took the regency. In his will, Alexander had stipulated that if he died, a council of regents chaired by Paul should govern until Alexander's son Peter II came of age.Prince Paul, far more than Alexander, was Yugoslav rather than Serb in outlook (Yugoslavism versus Serbian nationalism). However, unlike Alexander, he inclined much more toward democracy. In its broadest outline, his domestic policy worked to eliminate the heritage of Alexander's centralism, censorship, and military control and to pacify the country by solving the Serb-Croat problem.
