Kpengla was a King of the Kingdom of Dahomey, in present-day Benin, from 1774 until 1789. Kpengla followed his father Tegbessou to the throne and much of his administration was defined by the increasing Atlantic slave trade and regional rivalry over the profits from this trade. His attempts to control the slave trade generally failed, and when he died of smallpox in 1789, his son Agonglo came to the throne and ended many of his policies.

Agonglo was a King of the Kingdom of Dahomey, in present-day Benin, from 1789 until 1797. Agonglo took over from his father King Kpengla in 1789 and inherited many of the economic problems that developed during Kpengla's reign. Because of the poor economy, Agonglo was often constrained by domestic opposition. As a response, he reformed many of the economic policies and did military expeditions to try to increase the supply for the Atlantic slave trade. Many of these efforts were unsuccessful and European traders became less active in the ports of the kingdom. As a final effort, Agonglo accepted two Portuguese Catholic missionaries which resulted in a large outcry in royal circles and resulted in his assassination on May 1, 1797. Adandozan, his second oldest son, was named the new king.
