Why is reduccion and plaza complex effective as subjugation in Philippines?

The reduccion and plaza complex was effective in subjugating the Philippines because it centralized population in easily monitored and controlled areas, making it easier for Spanish authorities to exert influence and enforce colonial rule. By relocating indigenous communities to these planned settlements, the Spanish colonial government was able to exert control over the population and facilitate the spread of Christianity and Spanish culture. Additionally, the plazas functioned as centers for religious, social, and administrative activities, strengthening Spanish influence and authority in the region.
