This study examined the effects of elections on national security in Nigeria, with particular reference to the general elections in Edo State. It focused on four key objectives: examining the impact of electoral credibility, evaluating the role of voter education, assessing the effects of electoral violence, and determining the implications of electoral malpractices on national security. The research adopted a survey research design, which enabled collection of data through quantitative and qualitative means. The quantitative data were gathered through the use of Likert style questionnaire while the qualitative data were gathered through interviews with Key Informant Interview (KII) regarding their perceptions of electoral processes and its effects on national security. The study was guided by system theory and human security theory, which explain how the interaction between political institutions, citizens, and governance structures affects societal stability and individual safety. This study's population is made up of the men and women of voting age in Edo State which is 453,592 while the sample size for this study was 400 using the Taro Yamane formula. Three hundred and fifty six (356) respondents responded to the copies of questionnaire administered while twelve (12) interviewees responded to the interview guide. The findings revealed that electoral credibility is very significant in maintaining national security. The study also found that voter education contributes to national security by improving citizens’ understanding of the electoral process and discouraging manipulation and participation in political violence. The study recommends that strengthening credible electoral processes, enhancing voter education, and addressing electoral violence and malpractice are essential for promoting national security and democratic consolidation in Nigeria.
