This article analyses the trajectories of secularization, de-secularization and re-secularization in Bangladesh. It is about mapping broad historical developments with reference to basic understanding of secularization and its progress in Bangladesh. The central question in the article is: How have the trajectories of secularization, de-secularization and re-secularization in Bangladesh been influenced by the nexus of internal–external dynamics of political and social forces developed in the 1980s? The article argues that a decisive attempt to rediscover liberal and secular character of politics is currently evident in Bangladesh. The attempt to reestablish secularism in the society also faces a host of challenges, stemming from national, regional and global contexts that echo the 1980s. Methodologically, it is based on policy outlook and trend analysis.
