Polo y servicio
From WikiPilipinas: The Hip 'n Free Philippine Encyclopedia
Polo y servicio is the system of forced labor which evolved within the framework of the encomienda system, introduced into the South American colonies by the Conquistadores and Catholic priests who accompanied them. It was present in almost all of the Spanish colonial government around the world. Polo y servicio is the forced labor for 40 days of men ranging from 16 to 60 years of age who were obligated to give personal services to community projects. One could be exempted from polo by paying the falla (corruption of the Spanish Falta, meaning "absence"), a daily fine of one and a half real.
The system became the cause of many uprising against the Spanish colonial government around the world. The Sumuroy Rebellion exemplifies it.
