PREFACE
which enable us to piece together a fairly connected narrative. It
is clear that the Northern Sudan was subject to the Khalifas and
their representatives in Egypt, and that its rulers were compelled
by them to pay the " Bakt," or annual tribute of slaves. It is
equally clear, however, that the native Christian Church made a
persistent and gallant stand against Islam, and that Christianity
flourished in the country from the First Cataract to Soba on the
Blue Nile. The testimony of Muhammadan writers proves that
there were hundreds of churches in the country between these
limits, and we know from other sources that many of them were
fine buildings, the walls of which were decorated with painted
figures of saints, &c. The form of belief which the Sudan
Christians professed was that of Alexandria, i.e., Jacobite, and the
Liturgy was recited in Greek, and we may assume that the chief members of the clergy came from the Mother Church in Alex-
andria. In the thirteenth century, however, troubles came on the
native church, and, in proportion as the power and influence of
Islam grew and spread, Christianity declined. Little by little
mosques appeared in the towns and villages, and as the Patriarchs
of Alexandria were unable to assist the Sudan Church in stem- ming the flood of Muhammadanism which was sweeping over the
land, the clergy lost their hold upon the people, many of whom,
both voluntarily and under compulsion, rejected Christianity and became followers of the Prophet. The southern portion of the
Christian kingdom of the Siidan, that of 'Aiwa, came to an end
towards the close of the fifteenth century, and by the time Selim
conquered Egypt in 1517, the altars of Christ had been profaned or
overthrown, and the churches were forsaken buildings. When the
Arabs entered the Western Sudan from Tunis, and the Eastern Sudan from Masawa, and the Northern Siidan via Egypt, Islam
finally prevailed over Christianity, and, from about the year 1520
to the present time, the population of the whole Siidan has con-
sisted practically of Muhammadans and Pagans.
With the facts at present available it is impossible to write a
connected history of the country between 1520 and 1820, but we know that during this period Sultans ruled in Dar Fur, " Meks,"
or "Chiefs," in Shendi, Albanians in Nubia, and lines of heredi-
tary tribal Shekhs in other parts of the SM4n. These waged
