How biased or neutral/balanced were Jose Rizal and the Propaganda movement about late 19th century Spanish rule in the Philippines? Basically over here, all we have are historical sources written by Philippine nationalists and historians, which tend to lean left of center, and show things from a Filipino view, are there any pro-Spanish views, or Spanish sources in English, or more neutral sources about 19th century Spanish colonization in the Philippines?
