The Arabs, who are now to play their surprising part of history, are historically considered among the most important people of the Semitic race. The name ‘ Saracen ‘, applied to them is of a doubtful origin, but seems to come from the two Arabic words meaning “Sons of the Desert”. They are divided into two distinct classes: town and tent dwellers. It is to the latter class that the term ‘Bedouins’ is properly applied. Secured in their inaccessible deserts, the Arabs have never, as a nation, bowed their necks to any foreign conqueror, although parts of the Arabian Peninsula have been repeatedly subjugated by different invaders.
