Anti-Lithuanianism. The depth of contempt and dislike for Lithuanians in Poland is not something I can claim to like. A "people without culture" seems to be the attitute.
No, why do you think so? Honestly Lithuanians hate Poles (for the seizure of Vilnius by Poland in 1920s) - but not inversely.
And did you hear about the way how Lithuanian government treats Polish minority in Lithuania nowadays?
Despite the fact that we are both in EU, Polish minority in Lithuania is discriminated.
A bit ungrateful for the country that turned it into a great power.
Lithuania turned Poland into great power? Not really.
Lithuania had just the territory. Poland had the resources and the manpower and the money.
These combined formed a power, but not so great.
By the time of both unions - the personal from 1386 and the real from 1569 - Poland was a stronger country than Lithuania. Poland had much more population than Lithuania was better developed and had stronger economy. The only thing Lithuania had more of was territory.
The Union of Lublin in 1569 was signed because Lithuania could not resist against expansion of Moscow and needed Polish help. Even Lithuanians admit this (although they claim that Lithuania "was forced" to sign this union because of Moscow - while in fact it willingly wanted to do it).
Honestly Lithuania benefited much more from the Union of Poland than Poland did. Some Polish historians even write that the Union of Lublin from 1569 actually did more harm to Poland than good - and I agree with them.
If you know the history of both countries on a deeper level you would know this.
It was Lithuania who had real problems with Teutonic Order and it was Lithuania who had real problems with Moscow.
