Ukrainian is an Eastern Slavonic language closely related to Russian and Belarusian. It is spoken by about 51 million people in Ukraine (Україна) and in many other countries, including Argentina, Armenia, Azerbaijan, Belarus, Brazil, Canada, Estonia, Georgia, Hungary, Kazakhstan, Kyrgyzstan, Latvia, Lithuania, Moldova, Paraguay, Poland, Romania, Russia and Slovakia.
The recorded history of the Ukrainian language began in 988, when the principality of Kiev (Київ) was converted to Christianity. Ukrainian religious material, including translations of the Bible, was written in Old Slavonic, the language used by missionaries to spread Christianity to the Slavic peoples.
In the 13th century, Ukraine became part of the Grand Duchy of Lithuanian and Ruthenian, an ancestor of Belarusian and Ukrainian became the main language. The remaining parts of Ukraine were taken over by Poland during the 16th century and Latin and Polish were used for official purposes. Ruthenian began to split into Ukrainian and Belarusian during this period.
The Cossacks later moved into eastern Ukraine and during the 17th century, their leader, Bohdan Khmelnytsky, invited Russia to help against Polish domination in 1648. During the reign of Catherine the Great, the Cossacks moved to the eastern frontiers of Russia, but Ukraine remained under Russian domination, and the Russians considered the Ukrainian language as little more than a dialect of Russian.
Please note, the capital of Ukraine is written Київ (Kyiv) in Ukrainian, Kiev in English and Киев (Kiev) in Russian.
There are a number of systems for transliterating Ukrainian into the Latin alphabet. The system used here is the Ukrainian National transliteration, which is the official system used in Ukraine since 1996. It is used to write personal names in passports, and for geographical names on maps and road signs.
