At the outbreak of the First World War, Palestine (now Israel) was part of the Turkish Empire and it was not entered by Allied forces until December 1916.The advance to Jerusalem took a further year, but from 1914 to December 1917, about 250 Commonwealth prisoners of war were buried in the German and Anglo-German cemeteries of the city. Jerusalem War Cemetery was begun after the occupation of the city, with 270 burials. It was later enlarged to take graves from the battlefields and smaller cemeteries in the neighbourhood. Jerusalem War Cemetery was inaugurated on Mount Scopus in February 1918. There are now 2,515 Commonwealth burials of the First World War in the cemetery, 100 of them unidentified. Within the cemetery stands the Jerusalem Memorial, commemorating 3,300 Commonwealth servicemen who died during the First World War in operations in Egypt or Palestine and who have no known grave.
