THE UNWRITTEN RULE
Nigeria's constitution says nothing about rotating the presidency between North and South. The convention is a power-sharing pact engineered after the 1999 transition from military rule, designed to prevent any region from monopolizing federal power in a country with no ethnic majority.
THE THREE-NATION COUNTRY
Nigeria has roughly 250 ethnic groups, but three dominate politically: the Hausa-Fulani North (Muslim-majority), the Yoruba South-West (mixed Muslim-Christian), and the Igbo South-East (Christian-majority). The civil war of 1967–70 — when the Igbo South-East tried to secede as Biafra — killed perhaps a million people and still shapes who trusts whom.
THE IGBO EXCLUSION
Since 1999, every elected Nigerian president has been Hausa-Fulani (North) or Yoruba (South-West). No Igbo has held the office since the civil war. Obi's candidacy is the first serious push to close that 56-year gap — a structural grievance, not a personal ambition.
THE NORTH-SOUTH MATH
The North holds more registered voters than the South — roughly 54% to 46% of the 2023 register. A southern candidate cannot win on southern votes alone; the running mate is almost always northern, which is why Kwankwaso (Kano, North-West) is being floated as Obi's VP.
WHY THE NAIRA WATCHES THIS
Tinubu's 2023 win triggered a fuel-subsidy removal and a managed naira float that wiped out roughly 70% of the currency's dollar value in eighteen months. A 2027 challenger from a different zone would inherit the politics of either reversing or institutionalizing that pivot — markets read the zoning decision as the first signal.
