抗日戰爭爆發後，中國漫畫界所以能快速且熱烈地響應保土抗戰的號召，產生以畫筆當武器的抗敵效用，主要是因為漫畫深具強有力且通俗的宣傳作用。戰前的文藝，在通俗文化的發展及反日愛國風潮的激勵下，以上海為中心的新興漫畫團體開始推廣全國性的漫畫運動，不少漫畫家在「漫畫戰」的使命感驅使下，紛紛走上街頭、接近民眾，宣揚共赴國難、抗日救國的理念，並扮演教化文盲及政令宣導的代言角色。因此，漫畫在戰時成為最有說服力的宣傳工具之一，甚至是一種抗敵的有力武器。 戰前因出版「子愷漫畫」而頗富盛名的豐子愷，在抗戰爆發後，除了積極投入文藝界抗日宣傳的行列，並呼籲「漫畫是抗戰筆桿的先鋒」外，不同於致力宣傳漫畫的同行以及年輕漫畫家組織宣傳隊伍的是，他在堅守不作亡國奴的信念下舉家流難，輾轉遷徙、顛沛流離，又在重慶渡過六年近乎隱居的生活，遂以其豐富影像力與靈敏的感觸、結合詩文藝術的漫畫技巧，大量描繪了逃難歲月的點滴和社會底層的苦難。他的漫畫，無論是對日軍侵略的譴責、對軍民抗戰的鼓舞，或對人生無常及民間悲苦的批判，皆充分流露出他對生命本質的哲學思惟及悲天憫人的胸懷。 更值得一提的是，豐子愷本著將漫畫通俗化的理念，堅守漫畫藝術的本質，以戰爭與和平作為漫畫主軸的人生思考，呈現出一種特殊的人文與宗教關懷，使他終能超越當代漫畫家而啟迪世人。
