Ernst Adalbert of Harrach

Count Ernst Adalbert of Harrach (German: Ernst Adalbert von Harrach; Czech: Arnošt Vojtěch hrabě z Harrachu; 4 November 1598 – 25 October 1667) was an Austrian Catholic Cardinal who was appointed Archbishop of Prague and Prince-Bishop of Trento.

Ernst Adalbert of Harrach was born 4 November 1598 in Vienna, Archduchy of Austria, Holy Roman Empire as the son of Count Karl von Harrach and Maria Elisabeth von Schrattenbach.

Adalbert von Harrach was arrested at his palace when the Swedish took over a section of Prague in the precursor conflict to the Battle of Prague and lost a significant part of his wealth.

He was eventually released after intercession by cardinal Jules Mazarin before Queen Christina of Sweden, with 15,000 écus and a letter written by him promising not to take revenge for Adalbert von Harrach's losses.

[3] He visited Rome rarely; so much so that when he did in 1643, Pope Urban VIII is said to have considered it a bad omen (as the cardinal would only otherwise have visited had the pope died, requiring a papal conclave).
