Evan Enwerem was a Nigerian politician born in Ikeduru, Imo State, Nigeria, on October 29, 1935. He obtained his bachelor's degree from the University of Southampton in the United Kingdom.
Enwerem served as chairman of the Nigerian Airports Authority NAA between 1980 and 1983. He was also a member of the People’s Democratic Party and during the failed Third Republic era of Nigerian government in 1991, he was elected governor of Imo State.
Evan was elected to the Nigerian Senate in 1999 to represent the Imo-East Senatorial Zone. He became the first President of the Nigerian Senate during Nigeria's Fourth Republic. Enwerem beat his chief rival, Senator Chuba Okadigbo, for the Senate presidency on June 3, 1999. Former Nigerian President Olusegun Obasanjo backed Enwerem for President of the Senate against Okadigbo. With the support of the Obasanjo's allies in the governing parties, plus support from two Nigerian opposition parties, Enwerem easily defeated Okadigbo with 66 votes to Okadigbo's 43 votes.
In 1999, a Nigerian Senate committee began investigating Enwerem for allegations of corruption. The allegations against him was that he falsified his name, and caused a controversy as to whether Enwerem's actual real name was Evan or Evans. Enwerem was removed from office on November 18, 1999, in an ouster spearheaded by allies of Chuba Okadigbo. However, though removed as President of the Senate, Enwerem remained a member of the Senate until 2003.
Okadigbo, Enwerem's rival and successor as President of the Senate, was in turn removed from office on August 8, 2000. Following Okadigbo's 2000 ouster, Enwerem briefly expressed interest in again assuming the presidency of the Senate. However, Enwerem withdrew from the race in favor of Senator Adolphus Wabara at the shadow electionconducted by PDP Senators in Senate Hearing Room One.
Enwerem ultimately served as a Nigerian Senator from 1999 until 2003 before leaving office. On the 2nd of August 2007, He died due to his poor health condition at the age of 73 and is survived by his wife Vivienne, and seven children.
