After coming into power of the Saudi family the district of Riyaz, which is their capital, has become one of the important centres of Arabia. The length of Yemen, the south-western region of the Peninsula, is about 750 kilometres from north to south and about 400 kilometres from west to east and its area has be estimated to be sixty thousand miles. However, formerly its area was even more than this and during the last half century part of it (Aden) remained the protectorate of Britain.
