The Revolt of Islam is a poem composed by Percy Bysshe Shelley in 1817 and published in 1818. The poem was originally titled Laon and Cythna. The plot centres on two characters named Laon and Cythna who initiate a bloodless revolution against the Sultan of the Ottoman Empire. Despite its title, the poem does not have anything to do with Islam in particular, though the general subject of religion is addressed. Shelley identified and aligned himself strongly with the then-shocking notion of atheism. Shelley's work though, responding to the religious excesses and embedded hypocrisy of his time, is expressly spiritual, albeit running counter-religiosity.
