Non-Colonial 19th Century Filipino History Topics?

I'm in a course at my school called "Decolonizing the 19th Century" and figured this was a great opportunity to learn more about the Philippines considering the amount of colonization they've been through. My school encourages to use their library and EBSCO, both mainly having colonial topics.
What are some of your guys' favorite topics? Cities, communities, people, culture, etc etc. I'd really be interested in art and social studies
