Yes they were the strongest Baltic tribe and the only one able to defend themselves so their brainworms also come from having their own empire and then from having entire societal elite thoroughly polonised. But the teutonic shit is also there just from the second hand, since after Poland got partitioned the new Lithuanian nationalism and redefinition of nation came from petty bourgeoisie and unlike polonised nobility, Lithuanian bougies were germanised because basically all the cities in Baltics were full of German influence.
