Elisabeth was a Princess of Thurn and Taxis by birth and married Miguel Januário, Duke of Braganza, the Miguelist claimant to the throne of Portugal from 1866 to 1920.

Elisabeth was the daughter of Maximilian Anton, Hereditary Prince of Thurn and Taxis and his wife Duchess Helene in Bavaria.

Elisabeth died at the age of 20 in Ödenburg shortly after the birth of her third child, Maria Teresa.

[citation needed] Elisabeth's mother Helene withdrew more and more from public life after her death.

Elisabeth's husband Miguel Januário eventually remarried on 8 November 1893 in Kleinheubach to Princess Maria Theresa of Löwenstein-Wertheim-Rosenberg.
