The Nigerian election had been scheduled to take place in February, but was delayed for 6 weeks because of security concerns.
During that time, the Nigerian government launched a crackdown on the Islamist group Boko Haram, driving its fighters out of several towns and villages in the north.
Yinka Adegoke, Africa editor for news publication Quartz, says the government will want to build on that momentum, following the largely peaceful election, but that defeating Boko Haram will take more than military means alone.
"I think we have peace talks going on later this week, which talks about Niegeria winning the battle against the Boko Haram. The real issue is winning the war, and the war is the war against the root cause of the rise of something like Boko Haram," he said.
"Of course it's tied to religion, it's because of poverty, bad schools, unemployment. whoever wins, it almost doesn't who it is. Problems of Boko Haram is not temporary issues just dealt with military force."
