原因:No source. Borders seem inaccurate. The boundaries shown in this image differ from the ones shown in scholarly sources. For example, Joseph E. Schwartzberg's A Historical Atlas of South Asia shows the Khalji boundaries as depicted in File:Delhi Sultanate under Khalji dynasty - based on A Historical Atlas of South Asia.svg. The boundaries shown in this image are also contradicted by textual descriptions. . E.g.: According to KS Lal's History of the Khaljis (p. 220-221): "On the east .Turkish empire does not seem to have extended beyond Benares and Jaunpur (Sarju). Bihar and Bengal were ruled by Harasimka and Shamsuddin Firoz respectively, both independent of the Sultanate of Delhi.".
