It is situated in the Sivas-Samsun chausee, altitude 2280 ft., at the mouth of a rocky glen which opens out to the broad valley of the Tozanli Su, a tributary of the Yeshil Irmak.
Sinope, Kastamuni and Samsun were surrendered by the prince of Isfendiar, and the conquest of Asia Minor seemed assured.
The Turkish dominions in Asia Minor were extended, Amasia, Samsun and Janik being captured, and an insurrection of dervishes was quelled.
Its importance is largely due to its situation on the great trade-route from Kaisarieh (Caesarea) by Yuzgat and Marzivan to Samsun on the Black Sea.
Part of the kingdom was now annexed to the Roman Empire, being united with Bithynia in a double province called "Pontus and Bithynia": this part included (possibly from the first, but certainly from about 40 B.C. onwards) only the seaboard between Heracleia (Eregli) and Amisus (Samsun), the ora Pontica.
The sea-coast, like the rest of the south shore of the Euxine, was studded with Greek colonies founded from the 6th century onwards: Amisus, a colony of Miletus, which in the 5th century received a body of Athenian settlers, now the port of Samsun; Cotyora, now Ordu; Cerasus, the later Pharnacia, now Kerasund; and Trapezus (Trebizond), a famous city from Xenophon's time till the end of the middle ages.
SAMSUN (anc. Amisus), the chief town of the Janik sanjak of the Trebizond vilayet of Asiatic Turkey, situated on the S.
Samsun exports cereals, tobacco and wool.
Of Samsun, was, next to Sinope, the most flourishing of the Greek settlements on the Euxine, and under the kings of Pontus it was a rich trading town.
There is a good road to Aleppo and Alexandretta on the Mediterranean, and to Samsun on the Black Sea by Kharput, Malatia and Sivas.
East of Samsun, where the coast is partially protected by the Caucasus, the climate is more moderate.
About half of the total produce finds its way to the Chinese market, chiefly by sea to Hongkong and the Federated Malay States, although some is carried overland through Bokhara, Khokand and Kashgar; a small quantity is exported by way of Trebizond and Samsun to Constantinople, and about 2000 piculs to Great Britain.
Smaller quantities grown in Teheran, Tabriz and Kermanshah find their way to Smyrna, where it is said to be mixed with the local drug for the European market, the same practice being carried on at Constantinople with the Persian opium that arrives there from Samsun and Trebizond.
