Account for the coming of the Military into Nigerian politics in 1966?

REASONS FOR THE COMING OF THE MILITARY INTO NIGERIAN POLITICS IN 1966:

• Regionalization Of Political Parties: One
  of the causes of army take – over of government
  in Nigeria was the regionalization of political
  parties. The political parties tha existed in Nigeria especially during the
  first republic were regionally based. None of them
  had a broad national outlook and
  as a result they leaned on their various ethnic groups order to get support. This fanning of embers
  of ethnic consciousness proved injurious to the nation hence, the taking over of government by the military in
  order to save tr nation from imminent cataclysm. 
• Desire To Control The Federal
  Government: Politics, especially ethnic politics by nature, generates
  conflicts of varying magnitudes with consequences of different complexities.
  The desire to control the centre engendered ethnic
  political competition because, the politicians view the control of the Federal Government by any
  political party, as automatic control by the ethnic group where the party was
  rooted. This will afford them the opportunity to share and get more of the national cake. This acrimonious
  ethnic politics competition attracted the army
  who acted as unbiased umpire. 
• Tribalising And Politicizing The
  Army: The Nigerian army ‘ the
  first republic was tribalised and politicized. The army V used by the politicians to achieve what they
  failed to achieve through the ballot boxes. 
• Corrupton And Nepotism: Large
  scale corruption and nepotism that pervaded the first
  and second republics, played a
  major role in the military intervention in politics in Niger! Corruption and
  nepotism took the form of looting of public treasury,
  parading of ill-gotten wealth before the hungry and-toiling masses, the appointment and
  promotion of civil servants and distribution of amenities based on ethnic
  factors, etc. The above evils prepared the stage and acted as open invitation
  for military intervention in Nigeria’s body polity. 
• Economic Mismanagement:
  The military comes to power with
  the hope of righting the economic wrongs done by the civilians. The civilians embarked on
  prestigious and economically
  unviable projects with the aim of getting “ten percent” all these ruined the
  economy and invited the khaki boys to power.
• Mal-Administration: Bad administration in Nigeria has contributed to frequent coups that
  occurred in the country. Many square pegs
  who found themselves in round holes through ethnic’support failed to
  administer the country very well hence the intervention of the military. 
• Foreign
  Influence: The frequent coups we have experienced in Nigeria nay Africa
  had foreign influence as contributing  factors. The so – called big powers support
  and even sponsor the removal of any administration that fails to dance to their whims
  and caprices. 
• Influence
  Of Other Coups: Coups on African continent tend ,to be infectious. Despite
  the prevailing conditions at the time coup d’etat took place, Nigeria’s first coup was
  mainly influenced by the coup of
  January 1966 in the Central African Republic
  which ushered in Colonel Jean Bokassa, as
  well as the Colonel Lamizana putsch in Upper Volta now Burkina Faso on January
  4, 1966.
