The "Mad King" responsible for the fairy-tale Neuschwanstein Castle was King Ludwig II of Bavaria. Reining from 1864 to 1886, Ludwig was a romantic dreamer who preferred the arts and the operas of Richard Wagner over the grim realities of 19th-century politics. He built Neuschwanstein not as a defensive stronghold, but as a theatrical retreat and a monument to the Middle Ages. His "madness" is still debated in 2026; while he was declared insane by a government commission to remove him from power, many modern historians believe he was simply an eccentric introvert who bankrupted his own private fortune (not the state) on his building projects. His life ended in mystery in 1886 when he was found dead in Lake Starnberg just days after being deposed. Today, his "madness" provides Bavaria with its most lucrative tourist asset, as the castle famously served as the inspiration for Disney's Sleeping Beauty Castle.
