The major opposition party at the national level in Nigeria's Second Republic was the Unity Party of Nigeria (UPN). The Second Republic of Nigeria was the period between 1979 and 1983 when Nigeria had a democratically elected government. The UPN was a progressive party that was in opposition to the ruling party at the time, the National Party of Nigeria (NPN). The UPN was founded by Chief Obafemi Awolowo, a prominent Nigerian politician and statesman. The party was known for its socialist policies and advocacy for free education and healthcare. The UPN won significant support in the western part of Nigeria, but was unable to gain a majority at the national level, resulting in the NPN forming the government.
