In Berlin, Kleiber's scrupulous musicianship and enterprising programming won him a high reputation, but after the Nazi Party came to power in Germany in 1933, he resigned in protest against its oppressive policies, and left the country, basing himself and his family in Buenos Aires. For the rest of his career he was a freelance, guest conducting internationally in opera houses and concert halls. He played an important part in the creation of the Royal Opera in London, but a plan for him to return to the Berlin State Opera in the 1950s fell foul of politics.
