The breakup of the Ottoman Empire set thousands upon thousands of forlorn refugees on the move. Most western chronicles of this era focus only on those of the Christian faith who suffered. TCA is now publishing an annotated map displaying the trails of 5 million Ottoman Muslims who were displaced from the Balkans, Caucasus, and Crimea between 1770-1923. The map also records and provides historical context for the 5 million Ottoman Muslims who died between 1864-1922 in the wars that were fought to dismantle the Ottoman Empire. Prepared by Justin McCarthy, Professor of History at the University of Louisville, the map is a powerful visual tool for both the historian and the casual viewer who seeks better to understand the cataclysm that effected so many millions, Muslim and Christian alike, during the final years of the Ottoman Empire.
