The Report of the International Commission to Inquire into the Causes and Conduct of the Balkan Wars is a document published in Washington D.C. in 1914 by the Carnegie Endowment for International Peace. The International Commission consisted of university professors and other prominent individuals from France, Great Britain, United States, Germany, Austria and Russia. Among the members of the Commission there were three Nobel Prize winners. The Commission went to the participating countries at the beginning of August 1913 and remained until the end of September. After returning to Paris all the material was processed and released in the form of a detailed report. The report speaks of the numerous violations of international conventions and war crimes committed during the Balkan Wars. The information collected was published by the Endowment in the early summer of 1914, but was soon overshadowed by the beginning of the First World War. According to Mark Levene in 2020, the report is "thoroughly documented and still highly regarded". The Carnegie Endowment reissued the report uncritically in 1993, leading some to criticise the decision for anachronism and reinforcing the stereotype of 'Balkan violence'. Maria Todorova has discussed the reissued report (and its introduction by George Kennan) as an example of 'Balkanism'.
