Important Sources and References (6) A/ Since the appropriate and chosen methodology for this research is the historical method, I have focused on documents that cover the research period and its subject, especially British documents preserved in the National Archives in Khartoum. These documents cover several aspects, including the position of the British government in London and its administration in Sudan, documents about the activity of the Ethiopian resistance internally and in Sudan, in addition to regular British intelligence reports from Addis Ababa about the internal situation in Ethiopia in the period preceding the Italian invasion. Finally, British documents covering the problems and solutions of the border issues between Sudan and Ethiopia and the Nile waters.

B/ I also used interviews to fill in some aspects of the research, especially those related to Sudan – the Ethiopian presence in Sudan, support for the resistance, the period of Haile Selassie's stay, his activity in gathering Ethiopian refugees and resistance fighters, and his relationships with Sudanese leaders and symbols at the time.

C/ In addition to the abundant information I found in a number of university research papers and theses (unpublished) at the Center for African Research and Studies at Cairo University.

D/ I also consulted a number of Arabic and English references published in Sudan, Europe, and Ethiopia, including books, official publications, articles, and newspapers that covered the occupation period.
