Seven Pillars of Wisdom by T.E. Lawrence

A first difficulty of the Arab movement was to say who the Arabs were.

Being a manufactured people, their name had been changing in sense slowly year by year. Once it meant an Arabian. There was a country called Arabia; but this was nothing to the point. There was a language called Arabic; and in it lay the test. It was the current tongue of Syria and Palestine, of Mesopotamia, and of the great peninsula called Arabia on the map. Before the Moslem conquest, these areas were inhabited by diverse peoples, speaking languages of the Arabic family.
