General information

Ukraine is a country in Eastern Europe, bordered by Russia to the east and northeast, Belarus to the northwest, Poland and Slovakia to the west, Hungary, Romania and Moldova to the southwest, and the Black Sea and Sea of Azov to the south and southeast, respectively. It has an area of 603,628 sq km (233,062 sq mi), making it the largest country entirely within Europe and the 46th largest country in the world.
The country is home to 45.4 million people (including Crimea), 77.8% of whom are Ukrainians by ethnicity, followed by a sizeable minority of Russians (17%) as well as Romanians/Moldovans, Belarusians, Crimean Tatars, and Hungarians. Ukrainian is the official language of Ukraine; its alphabet is Cyrillic. The dominant religion in the country is Eastern Orthodoxy, which has strongly influenced Ukrainian architecture, literature and music.
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 Lithuania, Poland, the Ottoman Empire, Austria-Hungary, 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 later submerged fully into Russia. Two brief periods of independence occurred during the 20th century, once near the end of World War I and another during World War II, but both occasions would ultimately see Ukraine's territories conquered and consolidated into a Soviet republic, a situation that persisted until 1991, when Ukraine gained its independence from the Soviet Union in the aftermath of its dissolution at the end of the Cold War.
Ukraine is a unitary republic under a semi-presidential system with separate powers: legislative, executive, and judicial branches. Its capital and largest city is Kiev. Ukraine maintains the second-largest military in Europe, after that of Russia, when reserves and paramilitary personnel are taken into account.
Ukraine has long been a global breadbasket because of its extensive, fertile farmlands, and it remains one of the world's largest grain exporters. The diversified economy of Ukraine includes a large heavy industry sector, particularly in aerospace and industrial equipment.
