The greatest servant-leader of the past 1,000 years?

I recently ran across this post from the BBC, who did an online poll asking who was considered the 'greatest man' of the past 1,000 years. Here are the results:

1. Mahatma Gandhi
2. Leonardo da Vinci
3. Jesus Christ
4. Nelson Mandela
   
5. Sir Isaac Newton
6. Albert Einstein
7. Martin Luther King
8. Sir Winston Churchill
9. Charles Darwin
10. Karl Marx

Ok, this is quite the list! Considering the diversity, I would love to have seen the question so as to have a better idea of what exactly they were looking for. Since there are several servant-leaders on the list, let me ask:

Who is the greatest servant-leader of the past 1,000 years? For the sake of discussion, let's leave Jesus off the list for now. What names come to mind? Remember to think globally. If enough people leave comments or send me an e-mail, I'll post the results early next week.

In a similar story to the one above, English Head teachers would rather be like Gandhi than Churchill. Any surprise there?
