In
1459 A.C. Sultan Muhammad Abu Al-Futuh captured a number of
strategic seaports in the Mura lands thanks to Allah (Glorified be
He). Afterwards, he devoted himself to
overcome a Christian Greek state, which rose over the remains of
the Byzantine Empire in 1204 A.C. He attacked its capital that was
located on the Black Sea and seized it in 1461 A.C. He also took
its king, David Kominin, as a prisoner of war and he remained in
prison for a number of years.
In
1461, the Sultan took from them Amastria, which was a very
strategic location to the north of Anadul. Then, he seized Caffe
in 1475 A.C. and spread his complete sovereignty over all the
trade centers and the Black Sea turned to be an Ottoman Lake.
