Every revolution is born out of a dream. It may be the dream or vision of one person or a group of like-minded people, but it is the dream that sets the wheels of change in motion. This aspect is best illustrated in the case of post-colonial nations, especially India and Africa, where the colonizers were dethroned as a result of the revolutions triggered off by the natives" dream of a better future. Poet W. B. Yeats has said that In Dreams Begin Responsibilities, but unfortunately, many "visionaries" who dream of an "ideal" situation for their nations fail to shoulder the responsibilities that come their way. Soon, these visionaries themselves turn oppressors and the nation is on its way to being looter all over again. .
Chinua Achebe showcases such a situation in his novel, Anthills of the Savannah, wherein the fictional state of Kangan is ruled by the oppressive military dictator, Sam, who aspires to nominate himself "President for Life". As his oppressive tactics increase, we hear voices of dissent and see the people's dream of an improved Kangan and better conditions for themselves. Anthills of the Savannah traces the genesis and actualization of this dream through the life and ideals of Ikem Osodi - who provides the impetus - and Beatrice Okoh, who nurtures and sustains this dream.
Achebe's novel portrays a modern, independent, postcolonial, urban Africa. It dramatizes the socio-political struggle among Africans, and the continued Western influences on the economy and culture of Kangan, undeniable similar to Nigeria. The novel showcases the problem of the corrupt, dictatorial rule set up in Kangan and most of the other "new" African states that let down the dreams and hopes that were associated with independence: "Although the rulers were no longer European they fairly soon distanced themselves from the people .". Here Sam can be seen as the prototype of the military dictators, the ruthless megalomaniacs who sadly possess "both the yam and the knife".
