Ever wondered just how rich the richest world leaders really are? To put it in perspective, President Obama may be worth several million dollars, but he does not even come close to some of his contemporaries.
Based on available data, HuffPost World has compiled a list of some of the richest world leaders currently in power. The roster includes a mixture of kings, presidents, sultans and queens. Most are male (as the world's political leaders tend to be, too). They skew to the Middle East, and their wealth generally comes from family connections, profitable investments and in some cases, corrupt rule. Unsurprisingly, many of their countries' citizens lead much, much humbler lives.
For comparison, each country's GDP per capita is juxtaposed with a leader's personal net worth, just to show how different life is for the haves and have-nots.

Editor's Note: Sonia Gandhi and the former emir of Qatar Hamid bin Khalifa al-Thani have been removed from this list. Gandhi was originally included based on a listing on a third party site which was subsequently called into question. Our editors have been unable to verify the amount, removed the link, and regret any confusion. Qatar's emir was succeeded by his son Tamim in 2013.
