Dante Alighieri (c. 1265–1321) was a Florentine poet, philosopher, and political thinker whose epic poem the Divine Comedy is widely regarded as the greatest work of Italian literature and one of the foundational achievements of Western culture. Born into a family of minor nobility in Florence, he received a broad education in classical literature, theology, and scholastic philosophy, and was profoundly shaped by his unrequited love for Beatrice Portinari, whom he glimpsed only a handful of times but who became the idealized spiritual muse of his poetry, first in the early Vita Nuova and later as his celestial guide in Paradiso. Active in Florentine civic life, Dante served as a prior of the city and aligned with the White Guelph faction, but when the rival Black Guelphs seized power in 1302 he was sentenced to permanent exile under threat of being burned alive if he returned—a banishment that defined the rest of his life and embittered his political writing, including the Latin treatise De Monarchia, which argued for a universal secular empire independent of papal authority. During his wandering years through the courts of northern Italy, he composed the Divine Comedy, a three-part allegorical journey through Hell, Purgatory, and Paradise written in vernacular Tuscan rather than Latin—a radical choice that helped establish Italian as a literary language and earned him the later epithet il Sommo Poeta, "the Supreme Poet." He died in Ravenna in 1321, shortly after completing Paradiso, and remains buried there despite centuries of Florentine requests for the return of his remains.
