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. A Cossack republic emerged and prospered during the 17th and 18th centuries, but its territory was eventually split between Poland and the Russian Empire, and finally merged fully into the Russian-dominated Soviet Union in the late 1940s as the Ukrainian Soviet Socialist Republic. In 1991, Ukraine gained its independence from the Soviet Union in the aftermath of its dissolution at the end of the Cold War. Before its independence, Ukraine was typically referred to in English as "The Ukraine", but most sources have since moved to drop "the" from the name of Ukraine in all uses.
There are different hypotheses as to the etymology of the name Ukraine. According to the older widespread hypothesis, it means "borderland", while some more recent linguistic studies claim a different meaning: "homeland" or "region, country".
"The Ukraine" used to be the usual form in English, but since the Declaration of Independence of Ukraine, "the Ukraine" has become less common in the English-speaking world, and style-guides warn against its use in professional writing. According to U.S. ambassador William Taylor, "The Ukraine" now implies disregard for the country's sovereignty. The Ukrainian position is that the usage of "'The Ukraine' is incorrect both grammatically and politically."
