Allada was the most powerful polity at the time. Most of the other polities in the region were tributary. However, by the second half of the 17th-century kingdom’s power was in decline. In the 1680s the kingdoms of Popo (Great Popo) and Whydah (Hueda) on the coast west of Allada broke away from its authority. In addition, the coastal Port (Offra) often came to rebel against the kingdom’s authority, and these rebellions were often supported by the Kingdom of Whydah. To add to these problems were displaced individuals by the expansion of Akwamu.
In the 1680s the Kingdom of Whydah broke away from Allada’s authority after competing with Allada for control of European trade. As a result, Whydah became the main centre of trade in the area
Expansion of Akwamu in the late 17th century led to a myriad of displaced peoples, many of whom moved from the Gold Coast to the west of the Salve Coast.
