Even in the Jewish settlements in Palestine, German tended to be the lingua franca. Many of the settlers wanted German, rather than Hebrew, to be the language of instruction in Jewish schools. It was accepted, without debate, as the official language of Zionist congresses. The Zionist office in Berlin saw itself as the headquarters of the world movement, and its members were calling for a German protectorate over the Jews, as well as over Islam. Many believed it was the big Jewish community of Salonika which had helped to push Turkey into the war on Germany’s side.
