Please do not refer to Czechia as Eastern Europe. It’ simply wrong: Czechia rejected the Eastern Christianity even before the Great Schism, it never was a part of the Russian Empire and it spent most of the last millennium as a part of the HRE. The only connection - being part of the former Eastern block was so long ago that in only 4 years Czechia will be a EU member longer than it was occupied by the USSR.
