Correct.
Prior to 1790 they were part of a Polish-Lithuanian Empire (not I believe as a co-equal but at least with some autonomy and dignity rather than being raped as Stalin did to them). Prior to that they were an Independent Nation, prior to that, they WERE the Rus empire (loose term based on the day and age) based in Kiev; and Moscow didn't even exist. From the first Viking settlers in the late 800's AD until 1790 (900 years of history), they were either Independent, or controlled all of the territory surrounding them.
But that doesn't mean anything because Russia defeated the Polish-Lithuanian Empire and took control of Ukrainian territory in 1790.
Putin... go F yourself.
