Princess Maria Amélia de Bragança, daughter of Emperor Dom Pedro I of Brazil and Amélie von Leuchtenberg by Friedrich Dürck, 1849.
In 1852, Maria Amélia fell in love with her cousin, Austrian Archduke Maximilian. Their engagement was never officially announced and soon after she contracted tuberculosis, dying in 1853 at the tender age of 22. Archduke Maximilian went on the become the ill-fated Emperor Maximilian the I of Mexico.
But that wasn’t the end of Maria Amélia’s story. Maximilian continued to cherish her memory until his death in 1867. In a last homage to his dead fiancee, as he was being stripped of his belongings to face the revolutionary firing squad, Maximilian tenderly removed from around his neck a small religious medallion Maria Amélia had given him so many years ago and asked that it to be sent to her mother for safekeeping.
