# bio (long form, separated for readability)
bio: |
  Mongkut took the throne in 1851 and immediately did something unusual: he crowned his younger brother Pinklao as Second King and told the country to honor him as an equal. His reign came at the hinge moment when Western powers were circling Southeast Asia, and rather than resist the pressure with isolation, he leaned into modernization — importing technology, reforming institutions, engaging diplomacy. On 18 August 1868, he accurately predicted a total solar eclipse, a feat that became a calling card for Siam's entry into the scientific age and earned him the posthumous title "the Father of Science and Technology." He died six weeks later. In the West, none of that mattered: he's remembered almost entirely through *The King and I*, a 1951 musical that turned him into a strutting exotic, a role that won Yul Brynner an Academy Award and has been legally banned in his own country ever since.
