Italy formally annexes Ethiopia after taking the capital Addis Ababa on May 5.

The Ethiopian Empire, historically known as Abyssinia or simply Ethiopia, was a sovereign state that encompassed the present-day territories of Ethiopia and Eritrea. It existed from the establishment of the Solomonic dynasty by Yekuno Amlak around 1270 until the 1974 coup d'état by the Derg, which ended the reign of the final Emperor, Haile Selassie. In the late 19th century, under Emperor Menelik II, the empire expanded significantly to the south, and in 1952, Eritrea was federated under Selassie's rule. Despite being surrounded by hostile forces throughout much of its history, the empire maintained a kingdom centered on its ancient Christian heritage.

Addis Ababa is the capital city of Ethiopia, as well as the regional state of Oromia. With an estimated population of 2,739,551 inhabitants as of the 2007 census, it is the largest city in the country and the eleventh-largest in Africa. Addis Ababa is a highly developed and important cultural, artistic, financial and administrative center of Ethiopia. It is widely known as one of Africa's major capitals.

May 5 is the 125th day of the year in the Gregorian calendar; 240 days remain until the end of the year.
