In the 16th century, around Ronsard (1524–1585), Joachim du Bellay (1522–1560) and Jean Antoine de Baïf (1532–1589), there formed a group of radical young noble poets of the court (generally known today as La Pléiade, although use of this term is debated), who began writing in, amongst other forms of poetry, the Petrarchan sonnet cycle (developed around an amorous encounter or an idealized woman). The character of "La Pléiade" literary program was given in Du Bellay's manifesto, the "Defense and Illustration of the French Language" (1549), which maintained that French (like the Tuscan of Petrarch and Dante) was a worthy language for literary expression and which promulgated a program of linguistic and literary production (including the imitation of Latin and Greek genres) and purification.
