This is the book I would recommend on the dissolution of Czechoslovakia into its constituent parts, Czechia and Slovakia. An excellent history of the events, as well as Czechoslovakia in the 20th century. The core thesis is persuasive, namely that the elites of Czechoslovakia (Klaus and Meciar, specifically) and their interests were responsible for its end, and not the nationalism of Slovakia, or conflicting nationalist histories (among other explanations). Great accomplishment.
