Madam Efunroye Tinubu

-
Born in the Egbaland of the Yoruba people of West Africa at the beginning of the nineteenth century, Tinubu learned commerce from her grandmother, a successful trader. As a young woman Tinubu married a local man and bore him two sons, but she was widowed following the family’s migration to the town of Abeokuta in 1830. Shortly afterward she met Adele, a deposed king of Lagos, married him, and moved with her new husband and sons to the coastal town of Badagry, where Adele was temporarily recognized as ruler. Tinubu arrived in Badagry at a time when the then illegal Atlantic slave trade was peaking on the eastern Slave Coast. Although her sons soon died, she used two slaves, allegedly a gift from her father, to trade between Abeokuta and the coast in slaves and other commodities. Never again blessed with children, she invested her growing income from trade in slaves and other retainers, beginning the process of amassing personal followers and expanding her commercial operations.

Nigerian Athletes Living Like Beggars In Glasgow

With the Games set to kick off on Wednesday, delegates from the participating countries are already on ground and could be seen on the streets of Glasgow, especially around the games village, rightly fitted with track suits bearing their national colours. This is in contrast to the Nigerian athletes, who confirmed that they have not been supplied with kits and as a result they are dressed in different colours. Only those participating in the track and field events have kits, from other events they took part in. Others have no kits says, a senior Nigerian athlete at the Games, “it is embarrassing seeing Nigerian athletes in tatters,” he continued, adding “some are even wearing bathroom slippers." “The athletics team was lucky to have their own personal kits from previous outings.
