(Cilicia Pedias, Κιλικία Πεδιάς). The capital of both sections of Cilicia was Tarsus and Mersin was its seaport. The Seljuks later captured it from the Byzantines and it then came under the Crusaders then the Seljuks again and finally the Ottomans captured it and it remained part of the Ottoman Empire until 1922. Administration The province of Mersin between 1923 and 1933 didn't include the western territories of the modern province, which then constituted the province of İçel with Silifke as its administrative center. In 1933, the provinces of Mersin and İçel were merged. The new province was named "İçel" and the city of Mersin was made its capital. The province was renamed to "Mersin" in 28 June 2002. Districts Mersin province is divided into thirteen districts four of which are actually included within the municipality of Mersin city (shown in boldface letters).

Economy The city of Mersin is one of busiest cities in Turkey. Due to the economic activity in this part of Turkey generated by the GAP Project Mersin is Turkey's biggest Mediterranean port, and also hosts an oil refinery and a free trade zone; there are a number of factories along the road between Mersin and Adana, manufacturing glass, detergents, fertilizers and many more. With all this activity a modern city has grown with a university and other major amenities. Tourism Mersin does not have the huge volume of tourists enjoyed by neighbouring Antalya or the Aegean coast, but Turkish people do come to this coast, especially now that the hotels have air-conditioning, and perhaps more to the mountain country behind where there are healing mineral water springs. In summer the hills are a popular retreat from the high humidity and extreme heat on the coast. West of Mersin includes bays, and little islands. Yacht touring is a tourism income in these areas.
