Shagari's NPN government ruled Nigeria's Second Republic under the 1979 US-style presidential constitution. Economic school: statist-developmentalist inheriting the Fourth National Development Plan (1981-85) calibrated on assumed $30+ oil — oil-price collapse 1981-82 produced current-account crisis, arrears to foreign contractors, and the April 1982 Economic Stabilization Act (import licensing, tariffs, expatriate labour restrictions) — a defensive rather than adjustment programme. Left-right axis: centre-right democratic politically; statist-nationalist economically with ethnic-regional patronage networks producing endemic corruption (Rice Deal scandals). Popularity / legitimacy: 1979 election Shagari won with plurality (controversial '2/3 of 19 states' ruling); August 1983 election re-elected him amid mass irregularities — the election fraud plus fiscal collapse triggered Buhari's December 31 1983 coup. Coherence: low — the 1979 constitution, four-year plan, and oil-price assumption all collapsed simultaneously; defensive 1982 Act failed to restore external balance.
