Through historical research this project analyzes primary and secondary sources such as journals, publications, textbooks and internet materials. The findings of the study revealed that Nigeria, like other participating British colonial territories felt the impact of the First World which began in Europe in 1914 and ended in 1918. Much of the fighting took place among the central powers. In 1917, the USA joined the war against Germany as a consequence of her submarine activities and intrigues in Mexico. The War had a negative political, economic and social impact on all nations, leading to the peace conference in Paris and the treaty of Versailles in June 1919. Nigeria played a very vital role in the drive to achieve this by providing military training as well as a training in citizenship for democracy and political leadership. A culture of peace, education and non-violence has been the norm in Nigeria since the post-war period. The aims of the paper therefore are to understand the state and the role of education during the war and post-war period in Nigeria, to analyze the role of education in fostering peace in the education and to recommend ways of maintaining peace in the education sector in Nigeria. It is therefore recommended in this paper that the Nigerian Educational Research Development Council, should formulate policies that will bring cohesion with a bid to balancing the gap between the North and the South, that Labour Unions should resolve issues with government on a round table conference and not through violence and strike actions i.e. the Nigeria Union of Teachers, government should not mix educational matter with politics and education personnel should be well remunerated and given maximum encouragement to enhance productivity in the sector.展开更多
