Paul I of Russia
Paul remained overshadowed by his mother for most of his life. His reign lasted four years, ending with his assassination by conspirators. 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.
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.
