Nwagboka
Nwagboka, or Onye-isi Ikporo-Onicha was a Nigerian queen, the last omu of Onitsha.
In 1886 she led the Ikporo Onitsha in a strike against Obi Anazonwu. This all-woman boycott of social duties was intended "to remind the community that no society can function without the duties and tasks performed by its women."
After Nwagboka's death in 1886 no successor was named to the omu-ship, and since then Onitsha has only had a male monarch.
