Nigerian election winner Muhammadu Buhari congratulated outgoing president Goodluck Jonathan for peacefully relinquishing power on 1 April, a day after becoming the first Nigerian politician to unseat a sitting leader at the ballot box.
In an unprecedented step, Jonathan phoned Buhari to concede defeat and issued a statement urging his supporters to accept the result, a signal of deepening democracy in Africas most populous nation that few had expected.
Exactly 5.15pm yesterday evening, president Jonathan called to congratulate me on my victory. For this I want all Nigerians to join me in congratulating and appreciating Mr. president for his statesmanship, Buhari said.
President Jonathan engaged in a strict campaign and with a worthy opponent. I extend my hand of fellowship. Looking forward to meet him very soon as we plan the transition from one administration to another. He will receive nothing but understanding, cooperation and respect from my team and me, and the good people of Nigeria, he said.
The 72-year-old general, who first came to power three decades ago via a military coup, campaigned as a born-again democrat intent on cleaning up the corrupt politics of Africas most populous nation.
The margin of victory - Buhari got 15.4m votes to Jonathans 13.3m - was enough to prevent any challenge. The rules state he must officially hand over on 29 May.
Jonathans Peoples Democratic Party (PDP) has been in charge since the end of army rule in 1999 but had been losing support due to several oil sector corruption scandals and killings by Islamist militants in the northeast.
The eyes of the world were focused on us to see if we would vote in a peaceful way and carry out our respective elections in an orderly manner. We have proven to the world that we are a people who have embraced democracy and a people who seek a government by, for and of the people, the general continued.
Cities in the largely Muslim north, where Buharis core support base lies, erupted in celebration.
Jonathans appeal to his supporters that nobodys political ambition is worth blood meanwhile helped calm their frustrations, reducing the chance of post-election violence that blighted the 2011 poll.
Despite the killing of more than a dozen voters by Boko Haram gunmen - who had pledge to derail the poll - the election was one of the most orderly in the countrys history.
Buhari took power in a 1983 coup only to be thrown out 18 months later by another general. He subsequently embraced democracy, running in several elections and despite losing always bounced back.
Oil-rich Nigeria remains a complex ethnic mix of 170m people speaking more than 500 languages, split between Muslims and Christians. Though they mostly live side by side in peace, many harbour disputes that politicians have often used to stoke violence that has worsened over the years.
As well as the Boko Haram insurgency Buhari must deal with the fallout from a dive in global oil prices in the last eight months which has hammered squeezed state revenues and forced two de facto currency devaluations.
