Family
Maria Theresia was the third child and second daughter of Karl Alexander, 5th Prince of Thurn and Taxis and his wife Duchess Therese of Mecklenburg-Strelitz. She was an elder sister of Maximilian Karl, 6th Prince of Thurn and Taxis.

Marriage and issue
Maria Theresia married Prince Paul Anthony Esterházy of Galántha, eldest child and son of Nicholas II, 7th Prince Esterházy of Galántha and his wife Princess Maria Josepha of Liechtenstein, on 18 June 1812 in Regensburg, Kingdom of Bavaria. Maria Theresia and Paul Anthony had three children:


 * Princess Maria Theresia Esterházy of Galántha (27 May 1813 – 14 May 1894), ancestress of Gloria, Princess of Thurn and Taxis

 * Nicholas III, 9th Prince Esterházy of Galántha (25 June 1817 – 28 January 1894)

Esterházy was a popular diplomat and Maria Theresia became admired by his contemporaries, especially during the Congress of Vienna. During his long tenure as Austrian Ambassador to the United Kingdom (1815-1842), she became a leader of fashionable society. She was invited to become one of the patronesses of Almack's, the centre of London social life: the patronesses had the final say as to who was and who was not socially acceptable. She was one of the most popular patronesses: due to her youth she was described as "a nice child".
