The Katipunan was Illuminati

In 1776, Adam Weishaupt of Bavaria founded the original Illuminati , which means "enlightened ones."
In the early 1800's, the Philippines was under the oppression of Spain.  However, well-to-do Filipinos were able to go abroad for their college education. When they went to Europe, historians say, they saw the liberal culture unlike that imposed upon them in their homeland. When they got back to the Philippines, they gave rise to the ilustrado class, the "enlightened ones".

At this point, it gets obvious.

They discovered a secret society in Europe, and decided to adopt it in the Philippines.

Information was passed by word of mouth until it reached the ears of Jose Matanza Dizon, the founder of the famous Katipunan.

The Katipunan had a whole lot of triangle stuff in it:

1. The hoods of the Katipon and Kawal classes, and the mask of the Bayani class, all bore a triangle containing the letters Z. Ll. B.

2. The society's name (Kataas-taasang, Kagalang-galang, Katipunan ng Mga Anak ng Bayan), when abbreviated, was triple K's. (KKK)

3. Pio del Pilar's flag, the flag used by the Katipuneros in Bicol, and one of the simple Katipunan flags had elements of a triangle.

4. The Katipunan originally used the triangle method of recruiting, as in a new member must recruit two well-trusted acquaintances who do not know each other, only the person in question.

So, personally, yes, I think our country's valiant liberators were illuminati.
