"Twenty Years' Residence among the People of Turkey: Bulgarians, Greeks, Albanians, Turks, and Armenians" is a historical account published in the late 19th century, edited by Stanley Lane Poole.

It is written from the perspective of an Englishwoman who has spent two decades observing and interacting with these communities, highlighting the nuances of their lives and the complex relationships between them. At the start of the work, the author discusses the lack of authoritative and comprehensive information regarding the Eastern Question, emphasizing the need for a reliable source that captures the diverse conditions of the people living under Ottoman rule. The preface elaborates on her extensive experiences in various provinces of Turkey, setting the tone for a nuanced exploration of the ethnic identities of Bulgarians, Greeks, and Turks, among others. The opening portion introduces us to the complicated historical context of the Bulgarians, detailing their struggles under Ottoman oppression, societal dynamics, and the development of their national identity while contrasting their experiences with those of other groups in the region.
