In reconstructing the events leading to the Prague Easter massacre of 1389, perhaps the deadliest anti-Jewish pogrom in the Bohemian lands prior to WWII, modern historian relied for the most part on literary sources. Yet, these sources composed in Latin, Czech, German and Hebrew pose many problems. Not only are there few historians who can interrogate all of them, which led to research being skewed based on the language skills of researchers, but the sources are highly problematic on account of their literary character. I revisit these sources, particularly those written in Latin, in order to contrast them and point out where they disagree with and even contradict each other. Where possible, I strive to explain these contradictions and disagreements by contextualizing the documents and by highlighting the agendas they reflect. Language of article: German
