The outcomes of the hewett treaty that proved to be disastour for ethiopia were
1. Loss of territory: The Treaty of Hewett, signed in 1884, resulted in the United Kingdom recognizing Italy's control over the territories of Eritrea and parts of northern Ethiopia, which led to a significant loss of territory for Ethiopia.
2. Increased vulnerability to colonial encroachment: The treaty indirectly opened the doors for other European powers to stake their claims on Ethiopian territory.
3. Political instability: The treaty led to tensions between Ethiopia and Italy, leading to the First Italo-Ethiopian War from 1895 to 1896. Ethiopia was able to defend its sovereignty and emerged victorious; however, the war resulted in significant casualties and social and economic disruption. Ethiopia's victory also led to tensions among European powers as they were forced to respect Ethiopia's territorial integrity.
4. Economic repercussions: Losing control over Eritrea and the valuable port of Massawa significantly harmed Ethiopia's trade and access to the Red Sea. Ethiopia was cut off from international trade, leaving it economically vulnerable and dependent on neighboring countries for access to sea routes.
5. Defining borders: The Hewett Treaty instigated a series of negotiations and treaties with European colonial powers to demarcate Ethiopia's borders. The process was long and complicated, leading to further territorial disputes and conflicts with neighboring African nations.
6. Ethiopian nationalism: The Hewett Treaty and the resulting Italian aggression fueled Ethiopian nationalism, leading to resistance movements and eventually the formation of a centralized Ethiopian state under Emperor Menelik II.
In conclusion, the Treaty of Hewett proved disastrous for Ethiopia due to the significant loss of territory, increased vulnerability to colonial encroachment, political instability, economic repercussions, border disputes, and the rise of nationalist movements.
