João Soares de Paiva in the context of "Peter II of Aragon"

In the Middle Ages, the Galician-Portuguese lyric, also known as troubadorism, from trovadorismo in Portuguese and trobadorismo in Galician, was a lyric poetic school or movement. All told, there are around 1680 texts in the so-called secular lyric or lírica profana (see Cantigas de Santa Maria for the religious lyric). At the time Galician-Portuguese was the language used in nearly all of Iberia for lyric (as opposed to epic) poetry. From this language derives both modern Galician and Portuguese. The school, which was influenced to some extent (mainly in certain formal aspects) by the Occitan troubadours, is first documented at the end of the twelfth century and lasted until the middle of the fourteenth, with its zenith coming in the middle of the thirteenth century, centered on the person of Alfonso X, The Wise King. It is the earliest known poetic movement in Galicia or Portugal and represents not only the beginnings of but one of the high points of poetic history in both countries and in medieval Europe. Modern Galicia has seen a revival movement called neotrobadorismo.

The earliest extant composition in this school is usually agreed to be Ora faz ost' o senhor de Navarra by João Soares de Paiva, usually dated just before or after 1200. Traditionally, the end of the period of active trovadorismo is given as 1350, the date of the testament of D. Pedro, Count of Barcelos (natural son of King Dinis of Portugal), who left a Livro de Cantigas (songbook) to his nephew, Alfonso XI of Castile.
