Queen Idia

Idia was the mother of Esigie, the Oba of Benin who ruled from 1504 to 1550. She played a significant role in the rise and reign of her son, being described as a great warrior who fought relentlessly before and during her son's reign as the oba (king) of the Edo people.[

Queen Idia was instrumental in securing the title of oba for Esigie following the death of his father Oba Ozolua. To that end, she raised an army to fight off his brother Arhuaran, who was subsequently defeated in battle. Esigie thus became the 17th Oba of Benin.

Esigie instituted the title of iyoba (queen mother) and conferred it on his mother, along with Eguae-Iyoba (Palace of the Queen Mother).

Victory over Igala people

Subsequently, the neighboring Igala people sent warriors across the Benue River to wrest control of Benin's northern territories. Esigie conquered the Igala, reestablishing the unity and military strength of the kingdom. His mother Idia received much of the credit for these victories as her political counsel, together with her magical powers and medicinal knowledge, were viewed as critical elements of Esigie's success on the battlefield.
