The world’s youngest leaders hail from across the globe — from democracies, monarchies, and dictatorships in Eastern and Western Europe, Asia, and the Middle East.
While seven of the eight leaders are men, the youngest — Vanessa D’Ambrosio, the 28-year-old captain regent of San Marino — is a woman.
Meet the world’s eight heads of state under 40:
7. Jüri Ratas, 38, is the new prime minister of Estonia (he was voted into office in November 2016) and the leader of the country’s Centre Party.
6. Saleh Ali al-Sammad, 38, is the leader of the Houthi militants, who control much of Yemen, including the capital, Sanaa. (The US is providing support to the Saudi-led coalition fighting the Houthis, and Yemen also has a separate provisional government with a president and prime minister.)
5. Macedonian Prime Minister Emil Dimitriev, 38, took power in January 2016 after his predecessor, Nikola Gruevski, agreed to step down following protests against Gruevski for alleged mass wiretapping of Macedonian officials.
4. Jigme Khesar Namgyel Wangchuck, 37, is the fifth king of Bhutan — a position he took on when he was just 26 and his father abdicated the throne. Wangchuck oversaw the institution of the country’s new constitution in 2008, and is encouraging democratization.

3. Sheikh Tamim bin Hamad Al Thani, 36, is the Emir of Qatar — a post he took over in 2013 from his father (who took power from his own father in a non-violent coup 18 years prior).

2. Kim Jong-un, who succeeded his father as supreme leader of North Korea in 2011, is just 33. He has continued to brutally repress opposition within the closed-off country and escalate testing of its nuclear missiles.
1. At 28, Vanessa D’Ambrosio, who is serving a six-month term as the captain regent of San Marino, a mountainous European microstate, is the youngest leader of any country in the world. D’Ambrosio will lead the country alongside her co-captain regent, Mimma Zavoli, until October 2017.
