Answer
Ludwig II was the king of Bavaria from 1864 until his death in 1886. He was only 18 years old when he ascended to the throne. His reign was marked by a series of extravagant building projects, including the construction of the Neuschwanstein Castle. He was also known for his eccentric behavior and his love of Wagner's operas. In 1886, Ludwig was declared insane and was removed from the throne.
