It covers an area of 603,628 km², with a population of about 41.5 million, and is the eighth-most populous country in Europe. The country's capital and largest city is Kyiv. The territory of modern Ukraine has been inhabited since 32,000 BC. During the Middle Ages, the area was a key centre of East Slavic culture, with the powerful state of Kievan Rus' forming the basis of Ukrainian identity. Following its fragmentation in the 13th century, the territory was contested, ruled, and divided by a variety of powers, including the Polish–Lithuanian Commonwealth, Austria-Hungary, the Ottoman Empire, and Russia.
