My picks of political leaders for the last 500 years by likelihood of lasting influence
1. George Washington
2. Sir Winston Churchill
3. Mohandas Gandhi
4. Meiji
5. Charles deGaulle
6. Mao Zedong
7. Otto von Bismarck
8. Napoleon Bonaparte
9. Peter the Great
10. Simon Bolivar
I hate Mao. I wish that I could instead put Sun Yat-Sen in the list.
I think your list is showing some chronological and geographical bias. (I mean, deGaulle? Really? I get that he's fairly big in terms of the 20th Century, but top 10 in the last five centuries?)
At least in the same class as those you listed are:
Suleiman the Magnificent
Mughal Emperor Akbar the Great
The Qianlong Emperor of China
Gustavus Adolphus of Sweden
William III of England
Shogun Tokugawa Ieyasu
Holy Roman Emperor Charles V
Holy Roman Emperor Ferdinand III
Ivan IV of Russia
Louis XIV of France
