Kyiv, like Rome, gets its name from a character in a legend- Rome comes from Romulus
and Kyiv comes from Kyi. Kyi was one of four siblings. The legend says that in the fifth
century, a family of three brothers and a sister -Kyi, Shchek, Khoryv and Lybid-started a
settlement on the banks of the River Dnipro.
The question is, were these siblings real people? Archaeologists know people lived in the
area in the sixth century and earlier, so some people think they were real. Other people think
that they were mythical. They say the names of the brothers and a sister come from
geographical features. For example, they think that "Kyi" means "high river bank". The other
brothers' names, Shchek and Khoryv, are similar to the names of nearby mountains: Mount
Shchekavytsia and Mount Khoryvytsia. The sister's name, Lybid, comes from the River Lybid
which is south of Kyiv.
The golden age of Kyiv was from the tenth to twelfth centuries, when it was a centre
of Kyivan Rus- a state of several Slavic tribes. The city was on trade routes between the
Baltic Sea, Constantinopole and the area north-east of the Black Sea. It became a very
important city in Europe.
The period between the twelfth and nineteenth centuries saw the borders of European countries
change many times, and with each change, new people came to Kyiv: Tartars, Lithuanians,
Poles and Russians.
In the twentieth century, fighting in World War II badly damaged the city, but when the
war ended, restoration started. Kyiv became an important centre for industry. Lots of people
moved to the city from other parts of the country. Kyiv changed a lot in the twentieth century,
but it has still got many historic buildings, and the surrounding hills make it a pleasant city to
live in.
