Turkey's capital Ankara is a fascinating city. Its population during the height of Roman power was about 200,000, roughly 3x what it was in the 19th century. After World War I, it became the base of Turkish resistance to allied plans to completely dismember the Ottoman Empire, and became the capital when the Republic of Turkey was formed in 1923. Its population is now over 5 million, and it's the country's second largest city. Check out the city's modern skyline in this drone video from Denizvisual.
