The club's name is likely to originate from Angola's first president Agostinho Neto's famous poem Sagrada Esperança (Sacred Hope).

The club was founded on December 22, 1976, by then Angola-state owned diamond company Diamang (now Endiama), which remains as its major sponsor.

In 2005, the club, managed by Mário Calado, won the league by having one point ahead ASA.

The club plays their home matches at formerly Quintalão do Dundo, now Estádio Sagrada Esperança, which has a maximum capacity of 8,000 people [3].
