It was a quiet morning in May 1966. Across Nigeria, no one anticipated that a single signature in Lagos would dissolve regional powers, restructure governance, and change the daily lives of millions. One pen, one decree, and the nation would never look the same.
Between 1966 and 1999, Nigeria’s military rulers bypassed parliaments and courts, issuing decrees that became immediate law. These decrees were swift, absolute, and often far-reaching. Farmers, traders, civil servants, and journalists suddenly found their lives dictated by laws made without consultation, debate, or public input. The decrees shaped governance, civil liberties, the press, and even the very map of the nation.
What Was Rule by Decree?
A decree under military rule was a legal instrument signed by the head of state or military council. Unlike democratic legislation, decrees required no parliamentary approval, and courts could not challenge them. They were instruments of absolute authority, able to change constitutional arrangements, restructure states, and regulate civil society.

For Nigerians, decrees were more than abstract laws they were decisions that could alter livelihoods, freedoms, and identity overnight.
Decree No. 34: The Unification Decree
On May 24, 1966, Major General Johnson Thomas Umunnakwe Aguiyi-Ironsi signed Decree No. 34, also called the Unification Decree. It declared:
- Nigeria would cease to be a federation and become a unified republic.
- The Federal Military Government became the National Military Government.
- The Federal Executive Council was renamed the Executive Council.
- Regions were abolished and replaced by provinces under central authority.
Overnight, governance shifted from regional negotiation to centralized command. Farmers, civil servants, and traders had to report to new authorities they had never met. Loyalties, rights, and everyday administration were disrupted, demonstrating the power a single signature held over millions.
Although the decree was formally repealed later that year, its legacy endured. Centralized governance persisted, and state creation became a tool for political control.
States and Governance Transformed
After the counter-coup in July 1966, Lieutenant Colonel Yakubu Gowon assumed power. He reversed some aspects of Decree No. 34 but consolidated authority by creating 12 states in 1967, fragmenting old regional power bases.
Successive military regimes expanded state creation:
- 19 states in 1976
- 21 states in 1987
- 36 states by the early 1990s
Each new state reshaped local politics, altered resource allocation, and changed citizens’ sense of identity. Some celebrated their new autonomy, while others felt marginalized or erased. In all cases, a decree determined the boundaries of lives and governance.
Civil Liberties Under Decree
Press and Expression
Military decrees also redefined freedom of speech. Newspapers could be restricted, publications banned, and journalists tried by military tribunals.
During Buhari’s regime in the 1980s, Decree No. 4 (Protection Against False Accusations) criminalized criticism of the government. Journalists faced arrest and harassment, yet some defied the rules, smuggling stories that later became historic records of courage. Under Babangida, certain decrees allowed proscription of newspapers without judicial review, showing how decrees controlled narratives and public perception.
Detention and Rule of Law
Other decrees allowed detention without trial, removed judicial oversight, and placed military authorities above ordinary law. Individuals could be imprisoned indefinitely on government orders, highlighting the absolute power of military rulers and the fragile state of civil liberties.
The Human Impact of Decrees
Decrees were not just laws they were instruments that touched millions of lives. Families were affected by new state boundaries, businesses altered by economic decrees, and journalists challenged by press restrictions. Education, public service, and even local governance were subject to sudden change. Ordinary citizens experienced the human consequences of centralized power, making the abstract concept of law tangible and immediate.
Legacy of Military Decrees
When Nigeria returned to civilian rule in 1999, the 1999 Constitution restored democratic governance, but the shadow of military decrees remained. State structures, presidential authority, and federal resource allocation still reflect the imprint of military rule. Decrees shaped governance practices, centralized decision-making, and left a lasting influence on debates about federalism and restructuring in Nigeria today.

Military decrees remind us that laws are not just words they are instruments of power, capable of shaping nations and affecting lives at every level.
Author’s Note
Military decrees in Nigeria were more than laws; they were instruments of power that touched every citizen, reshaped governance, and altered lives overnight. This article tells the story of how one signature could dismantle regional authority, change the structure of the state, suppress civil liberties, and leave a lasting imprint on Nigeria’s political DNA. Understanding these decrees offers insight into the nation’s past and why debates about federalism, power, and governance remain urgent today.
