After three years with her paternal grandmother, Alexandra left Florence to continue her studies in the United Kingdom, while her mother settled in Venice. Separated from her mother, the princess fell ill, forcing Aspasia to make her leave the boarding school where she was studying. After the restoration of her uncle, King George II, on the Hellenic throne in 1935, Alexandra stayed in her native country several times but the outbreak of the Greco-Italian War, in 1940, forced her and her mother to settle in Athens. The invasion of Greece by the Axis powers in April–May 1941, however, led to their moving to the United Kingdom. Again exiled, Alexandra met in London the young King Peter II of Yugoslavia, who also went into exile after the invasion of his country by the Germans.
