THE ARAB EMPIRE
language, and their primitive paganism was successfully challenged
only by the coming of Islam.
The first serious attempt at Arab colonization, as distinct from
mere raiding, was made by Okba, who is revered by his co-
religionists to this day as the founder of Muslim Africa. By planting
a permanent camp at Kairawan in 670, he threatened alike the
Byzantines and the Berbers: by undertaking his famous march to
the West more than ten years later, he boldly claimed the whole
continent for Islam and brought the Arabs to the verge of Europe.
How much is truth and how much legend in the story of this grand
razzia, is impossible to say. Starting from Kairawan, and avoiding
the Byzantine towns and forts north of the Awras, he struck across
the central plateau, pushed beyond the Atlas, reached the coast at
Tangier, turned south into Morocco, and followed the course of the
river Sus to the point where it discharges into the Atlantic. Spurring
his horse into the waves (so runs the tale), and raising his lance
aloft, he cried, like a new Alexander, ‘Great God, if my advance
were not stopped by this sea, I would still go on, to the unknown
kingdoms of the West, preaching the unity of thy holy name, and
putting to the sword the unbelieving nations who worship other
gods than thee!’ His ruthless treatment of the Berbers provoked a
rising of the tribes under one Kusaila, and on his return journey
he fell into an ambush on the edge of the Sahara near the modern
Biskra, and perished with all his men (683). Kusaila occupied
Kairawan, with some help from the Byzantines, and though the
place was recovered and the Berber leader killed three years later,
the Arabs were faced by a new native revolt, this time among the
more nomadic tribes led by a woman, a kahina or prophetess, a
Berber Deborah. No further progress was made until Abd al-Malik
had restored peace at home and a new series of revolutions in
Constantinople paralysed Byzantine resistance in North Africa.
In 695 the Emperor Justinian II, a crazy tyrant and the last of
the line of Heraclius, was deposed and exiled, and for mere than
twenty years coup succeeded coup in Constantinople, until order
was restored by Leo III the Isaurian in 717. It was during this
interval that the last and most startling of the Arab conquests were
made in the West, and North Africa and Spain were torn away
from Christendom. The Caliph sent a new army under Hassan b.al-
Nu‘man, who by a bold surprise attack seized Carthage, but was
