Ilaro town, western Ogun state, southwestern Nigeria. Located on the former trade route from the towns of the empire of Oyo to the port of Porto-Novo (now the capital of Benin), 40 miles (64 km) southwest, it was established by the late 18th century as the capital and chief trade centre of the Egbado people (a subgroup of the Yoruba). With the decline of Oyo in the early 19th century, the Egbado kingdom was raided for slaves by the Dahomeyans until it was absorbed in the 1840s and ’50s by the more powerful Egba kingdom at Abeokuta (29 miles [47 km] northeast). As a subject town, Ilaro served the Egba as a trading post on the western route from Lagos to Ibadan. In the 1860s European missionaries arrived and established the Yoruba Anglican Mission in Ilaro. Following the 1890 delineation of colonial boundaries by the French and the British, the Egbado , who felt oppressed by Egba rule, asked for British protection and control of their territory. A British military garrison was built in Ilaro in the same year.
Modern Ilaro is a collecting point for cocoa, palm oil and kernels, kola nuts, vegetables (especially rice and okra), and fruits grown in the surrounding area. Yams, cassava, and corn (maize) are also cultivated by the town’s farmers. Cotton weaving and dyeing (with locally grown indigo) are traditional industries. There are deposits of limestone (used by a cement plant at Ewekoro, 13 miles [21 km] east-northeast) and phosphate in the vicinity.
