What is the theme in Dogeaters by Jessica Hagedorn?

The nation - and the national history - of the Philippines is a central focus of Jessica Hagedorn's Dogeaters. Early in the play, the playwright establishes the history of colonization and conquest that has shaped modern Philippine society. The conquistadors of Spain, French missionaries, American expansionists, the Japanese forces of World War II - all have had a hand in occupying the island nation, and all have left a mark.
