Now, as people in Africa's most populous country prepare to head to the polls Saturday, in what is set to be a tightly contested race, CNN takes a look at some of the most talked-about -- and somewhat bizarre -- moments of the campaign.
Nigerians Campaign ... In Ghana
As if the massive campaign rallies and the expensive advertising strategies within Nigeria are not enough, the nation's two main presidential candidates -- incumbent president Goodluck Jonathan and opposition leader Muhammadu Buhari -- decide to also take their fight for voters abroad.
Hoping to capitalize on the large numbers of Nigerians living in Ghana, both Jonathan's People's Democratic Party and Buhari's All Progressives Congress plaster many major streets in Ghana's capital, Accra, with posters of the parties' leaders.
The move, however, does not go down too well with officials in Ghana as local authorities promptly order the removal of all the election campaign posters in late January.
Caught On Tape?
An audio tape published by citizen journalism site Sahara Reporters on February 6 alleges that several prominent Nigerian politicians had conspired with the military to rig the 2014 elections in Ekiti State.
President Jonathan rules out investigating the allegations, saying the audio tape is "fabricated," according to reports in the Wall Street Journal. "It's all fabrications," he is quoted saying. "Why should I investigate things that are not real?"
We Need More Time
On February 7, the country's election commission announces the postponement of the elections, due to be held on February 14, for six weeks. The commission says the postponement is due to security concerns, after agencies say the military needs more time to secure areas controlled by extremist group Boko Haram.
The controversial decision is unpopular among many Nigerians and leads to widespread protests.
Torn to Pieces
In mid-February, former president Olusegun Obasanjo, an elder statesman and a key supporter of Goodluck Jonathan in the 2011 elections, publicly rips up his membership card of the People's Democratic Party. This marks a turning point in the relationship between Obasanjo and the Nigerian president, whom he'd previously mentored.
The event on February 17 causes a mini social media storm, with some pointing to reports that Obansajo ripped apart an old and invalid membership card.
Morocco's official news agency Map reports on March 10 that the country's ambassador has been recalled from Nigeria because King Mohammed VI had been used in an election campaign in Nigeria to win over Muslim voters. Nigeria's foreign ministry denies that there is a spat, saying President Jonathan had spoken to the king.
This in turn is denied by Morocco whose official news agency states: "The king has actually declined the request of the Nigerian government because it is part of the internal electioneering. The kingdom of Morocco expresses its astonishment and denunciation to these unethical practices that are contrary to the spirit of responsibility that must prevail in relations between states."
Appointment Causes Furore
On March 18, President Jonathan swears in Senator Musiliu Obanikoro, one of the politicians implicated in the "Ekitigate" allegation, to his cabinet. The appointment prompts a mass walkout by APC lawmakers, according to reports in Nigerian newspapers. Senate Spokesperson Enyinnaya Abaribe tells reporters that according to Nigeria's laws and constitution "anything that is a mere allegation and not a court decision is nothing but a mere allegation."
Show Us Your School Certificate
On March 25, after weeks of speculation and an ongoing legal battle over allegations that General Buhari failed to complete his secondary school education, a Nigerian court clears the way for the APC leader to run in the presidential race after adjourning the case until April 22.
Previously, chief Femi Fani-Kayode, director of media and publicity of PDP had issued a statement saying: "As long as he cannot produce that secondary school certificate, we believe that he is not qualified to run for the presidency of Nigeria. This is a matter of law and not sentiment."
The allegations had not been left unanswered by Buhari himself: "My examination number was 8200002, and I undertook the examination together with some prominent Nigerians including, late Shehu Musa Yar'Adua, and former President of Court of Appeal, Umar Abdullahi," according to Premium Times.
