Shortly after the end of the war, on 17 July 1945, Queen Alexandra gave birth to her only child, Crown Prince Alexander of Yugoslavia, in Suite 212 of Claridge's Hotel in Brook Street, London, which according to some reports was transformed for the occasion into Yugoslav territory by the British Prime Minister, Winston Churchill. However, the arrival of the heir to the throne was quickly followed by the deposition of the Karađorđević dynasty and the proclamation of the Socialist Federal Republic of Yugoslavia by Marshal Tito on 29 November 1945. This is the beginning of a long period of difficulties, marked by financial instability, the pursuit of vain political projects and the deterioration of relations between Alexandra and Peter II.
