Despite the uniqueness of these events and the precision of the situations and relations between the two countries and the colonial European countries, and the role that Sudan played in liberating Ethiopia and Eritrea and the return of the Emperor to his throne, it has not been studied. The political, economic, and military backgrounds of the Ethiopian struggle, and the analysis of the positions and the significance of the Ethiopian people's and officials' embrace of Sudan and their departure from it to liberate their country, despite their proximity to a number of other countries. It is not studied or analyzed the effects left by that period on the relationship between the two countries later. Undoubtedly, the study of the Italian occupation and the liberation campaign, in which Sudan played a role, is important in clarifying the nature of the relationship and the influences it encompassed.

It is needless to say that the phenomenon of asylum between the two countries recurred in later eras, and it is one of the results and effects of the event that this research deals with.

The importance of this research lies in its clarification of the circumstances, positions, and policies that encompassed the relationship between the two countries with each other and with the countries of the region and the surrounding environment.

From then on, Sudan became a refuge and sanctuary for Ethiopians fleeing political or economic hardship. Sudanese political parties and their leaders also benefited from the relationship that was strengthened with the Emperor in Sudan when political circumstances forced them to seek refuge in Ethiopia. Ethiopian refugees and exiles in Sudan formed a fundamental part of the political and military class that ruled after the liberation, and they had their influence on the relationship between the two countries, just as former exiles in Jerusalem also had an influence on Ethiopia's relationship with Israel.

Before this, the research sheds light on the colonial era and its effects on the countries and peoples of the region, and clearly explains the narrow colonial view and the policy of dividing interests and roles that these countries followed.

Also, the research aims to delve into the roots of the Sudanese national movement and the conditions in which it arose.
