At the end of the 19th century, Spanish carnivals have been marked by the participation of the different tunas or also known as, estudiantinas. These groups achieved significant relevance in Galicia, especially in the city of Compostela, which, year after year, encouraged and supported the formation of groups of this nature to liven up the carnivals in the different Spanish cities. Although, different from its predecessors, the Santiago Tuna of 1888 ventured and made its mark in history, thanks to its intrepidity in having been the first Galician group that crossed the borders and enlivened the carnivals in the cities of the neighboring country, Portugal. This research, approached from a historical and descriptive perspective, aims to carry out a review of the semblance Compostelana Estudiantina of 1888, through primary and secondary sources, and place it as an indispensable part of a tradition, which lasts until today.
