Harry Charles Lukach's 'Mosul and its Minorities' is a profound historical examination of the diverse ethnic and religious groups inhabiting the region of Mosul, Iraq. Published in 1925, this work offers a critical look into the social, cultural, and political dynamics of the time, particularly focusing on the status and interactions of its various minority populations. Lukach, drawing on extensive research and firsthand observations, sheds light on the complex tapestry of communities, including Kurds, Assyrians, Yazidis, and others, within the broader context of Ottoman decline and the formation of modern Iraq. It is an invaluable resource for understanding the historical intricacies and challenges faced by these groups, providing essential insights into the enduring legacy of diversity in one of the Middle East's most historically significant cities.
