In the sixteenth century, Spaniards forcibly resettled Andeans into planned towns called reducciones. Andeans adapted the political and religious institutions of the new towns, the cabildo (town council) and the cofradías (confraternities), and made them their own, organizing them by the Andean social form, the ayllu. Over time, political legitimacy and authority within towns was transferred from traditional native hereditary lords, the caciques, to the common people of the town, who called themselves the común. Although a Spanish word, común took on Andean meaning as it was the word used to translate terms for collective land and the collective people of a town. It became a recognized shorthand for a political philosophy empowering common people. In the late eighteenth-century era of Atlantic Revolutions, the común rose up against its caciques, in an Enlightenment-from-below moment of popular sovereignty.
