Ankara is the capital of Turkey and the country's second largest city after İstanbul.
Centrally located in Anatolia, Ankara is an important commercial and industrial city. It has been the neural center of the Turkish Government, and houses all foreign embassies. It is an important crossroads of trade, strategically located at the center of Turkey's highway and rail network, and serves as the marketing center for the surrounding agricultural area.
Modern ANKARA is really two cities, a double identity that is due to the breakneck pace at which it has developed since being declared capital of the Turkish Republic in 1923. Until then Ankara had been a small provincial city, famous chiefly for the production of soft goat's wool. This city still exists, in and around the old citadel that was the site of the original settlement. The other Ankara is the modern metropolis that has grown up around a carefully planned attempt to create a seat of government worthy of a modern, Western-looking state.
