Chwalba and Harpula have selected 10 turning points in Polish history where a single decision or other circumstances determined fundamentally important matters. In an absolutely fascinating conversation the authors consider scenarios in Polish history which did not actually take place but in all probability could have done and so they show that chance occurrences influence the fate of a nation. For example they analyse what would have happened if Poland and Lithuania had not entered into a union, what would have been the consequences of the Ukrainians becoming a third and equal partner in the Polish-Lithuanian Commonwealth and what might have happened had the majority of Poles been Protestants rather than Catholics. For each specific set of events the authors describe the main players and then review the other possible historical outcomes. They ponder over the potential consequences of these alternatives for both the past and the present day. This book raises pertinent questions about whether it was inevitable that Poland experienced the historical catastrophes it suffered or whether there had been opportunities for the country inhabited by Poles to become more powerful and more prosperous. While dealing with these questions the authors show that decisions taken centuries ago influence Poles’ current identity and the state of the country they live in. Changing Tracks is a historiosophic deliberation but at the same time it is enthralling entertainment. Its broad sweep, the extensive information presented and the academic precision contribute to a mental journey following alternative outcomes in Polish history which engages and fascinates the reader.
