Alerta Katipunan is one of the most popular songs from that revolution that survived to this day. Yet almost nothing is known about it and how it came to be one of the most beloved battle songs of the revolution, at one point used as an anthem.
For a long time, the history of this revolutionary song lingered in obscurity - the identity of the composer and its "Spanish military" origin remained unknown to us, until recent scholarships have finally revealed the concealed origins of Alerta Katipunan - with many more uncovered along the way.
I've taken the hassle to connect the existing evidences and accounts in order to uncover the origins and make a concise timeline to see how a Spanish loyal hymn became a battle song of the revolution.
