Meet The World's Royal Teenagers

Prince Dipangkorn Rasmijoti of Thailand is 15-years-old, and the son of Princess Srirasmi Suwadee and King Vajiralongkorn. He is the fifth son and seventh and youngest child of the King, but is the heir to the throne. The reason he is the heir even though he is the youngest is because the other children were disowned. 

Princess Srirasmi Suwadee was King Vajiralongkorn's third wife. He had four sons by his second wife, but after he divorced her in 1996, he disowned their children. This made Dipangkorn Rasmijoti the heir.
