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.
History of Russia
The invasion of Russia was a catastrophe for Napoleon and his 450,000 invasion troops. One major battle was fought at Borodino; casualties were very high but it was indecisive and Napoleon was unable to engage and defeat the Russian armies. He attempted to force the Tsar to terms by capturing Moscow at the onset of winter, even though the French Army had already lost most of its men. The expectation proved futile. The Russians retreated, burning crops and food supplies in a scorched earth policy that multiplied Napoleon's logistic problems. Unprepared for winter warfare, 85%–90% of Napoleon's soldiers died from disease, cold, starvation or by ambush by peasant guerrilla fighters. As Napoleon's forces retreated, Russian troops pursued them into Central and Western Europe and finally captured Paris. Out of a total population of around 43 million people, Russia lost about 1.5 million in the year 1812; of these about 250,000 to 300,000 were soldiers and the rest peasants and serfs.
