the large Christian population. While Sharia law is currently not implanted, there is a Sharia court that operates in the state, though pertains to Muslims only. Oyo State Since May 2002, attempts have been made to implant Sharia law into the southern Oyo State, which would legalize polygamy. Polygamous unions are currently recognized under customary law throughout Nigeria, but lack numerous benefits in a Nigerian civil marriage. While civil marriage in Nigeria is monogamous, a dozen states have implanted Sharia into their legal systems and thus are exempt. While the implanting of Sharia was unsuccessful, numerous Sharia courts were set up in Oyo State to serve for Muslim legal cases. Sharia has yet to be introduced to the entire state as the governing legal system. Plateau State Plateau State currently does not recognize polygamous marriages under civil law. Efforts to introduce Sharia law in Plateau State have resulted in several brutal clashes between Christians and Muslims due to strong opposition by the largely Christian population. As of 2018, Sharia law has not been implanted into the state's legal codes. Zamfara State After the adoption of Sharia Law in Zamfara State in early January 2000, Zamafara State became the first state in Nigeria to allow for legal recognition of polygamous marriage under civil law, as such is practicable under Sharia, which allows for a man to take up to four wives on the account that he treats them equally. Mahmud Shinkafi, the governor of Zamfara State, has two wives. After Zamfara State established Sharia which brought about polygamy, numerous other states such as Kano State soon followed suit, thereby legalizing polygamy. While the Government of Nigeria only recognizes a monogamous marriage under civil law, recognizing polygamous unions with similar benefits under customary law, states that impose Sharia are not affected by such and therefore can provide polygamy for their citizens.
