#5 Nikolai Alexandrovich Romanov - Net Worth $300 Billion
Nikolai Alexandrovich Romanov, also known as Tsar Nicholas II of Russia, ruled the Russian empire from 1894 to 1917 when Bolshevik revolutionists overthrew and murdered him and his family. In 1916, Tsar Nicholas II's net worth was nearly $900 million which is the inflation adjusted equivalent to $300 billion in 2012 dollars. $300 billion makes him the fifth richest person in history and since the Russian Orthodox canonized him, he is the richest saint in human history.
