Question: Which countries comprised the alliance that conquered and occupied Greece? Passage:Aside from the Romaniotes, a distinct Jewish population that historically lived in communities throughout Greece and neighboring areas with large Greek populations, Greece had a large population of Sephardi Jews, and is a historical center of Sephardic life; the city of Salonica or Thessaloniki, in Greek Macedonia, was called the "Mother of Israel". Greek Jews played an important role in the early development of Christianity, and became a source of education and commerce for the Byzantine Empire and throughout the period of Ottoman Greece, until suffering devastation in the Holocaust after Greece was conquered and occupied by the Axis powers despite efforts by Greeks to protect them. In the aftermath of the Holocaust, a large percentage of the surviving community emigrated to Israel or the United States.

Question: How long had Sydney been established the year that Bob Heffron moved there to become the secretary of the New South Wales branch of the Federated Marine Stewards' and Pantrymen's Association of Australasia? Passage:In 1921, the Heffrons moved to Melbourne, Victoria. That same year in Victoria, Heffron was appointed an organiser for the Federated Clothing Trades of the Commonwealth of Australia and also joined the leftist Victorian Socialist Party. Later in 1921 he moved to Sydney, becoming the secretary of the New South Wales branch of the Federated Marine Stewards' and Pantrymen's Association of Australasia. As the union's state secretary, a role he would hold for ten years, he took a prominent role in maritime trade unionism in Sydney. In February 1924, when the Commonwealth and Dominion Line steamer Port Lyttelton was declared 'Black' by the Labor Council of New South Wales owing to various worker's disputes and the ship having been declared unseaworthy, Heffron and six other union representatives acted to advise members of the Seamen's Union to refuse to work on the Port Lyttelton. For this, in April the government of Sir George Fuller had Heffron and the six other unionists arrested on the charge of conspiracy to strike action. Although controversially refused bail by the trial judge, Heffron and his fellow defendants, represented by Richard Windeyer KC and H. V. Evatt, were found not guilty and released in July 1924 by the court, a verdict that had been returned by the direction of the judge. Later joining the Labor Party, at the time he showed himself to be a supporter of party leader Jack Lang, supporting Lang's successful motion at the 1923 state conference to readmit James Dooley to the party.
