The book is devoted to the issue of cultural and institutionalized ties between Czechs and Slovaks, or rather Czech-Moravians and Slovakia, at the state level. After all, there was Czechoslovak statehood for most of the 20th century. It was created on the ruins of the "Austro-Hungarian prison of nations," which had been broken up in the name of pursuing the dogma of self-determination of nations. This led to the creation of Czechoslovakia, where, according to the prevailing ideology, the state-creating nation was Czechoslovakia, which was a synthesis of Czechs, who had played a significant role in Central European history, and Slovaks, who had been under Magyar rule for many centuries.
