Piers Plowman, a 14th-century allegorical poem by William Langland, offers a scathing critique of medieval English society and the Catholic Church. Set against the backdrop of social upheaval following the Black Death, it reflects growing discontent among the peasantry and the influence of reformist movements. The poem follows Will, a dreamer seeking spiritual truth, through a series of dream visions. Using alliterative verse and complex symbolism, Langland explores themes of corruption, social justice, and personal salvation, while advocating for the dignity of honest labor and the need for religious reform.
