Who is the master of history in the world?

This question presents a fallacy, making the question nearly impossible to answer without a point of reference. The world, is to broad in terms of defining "who is the master", making the title of "World History" useful only to high school textbooks. History of the world would technically encompass every aspect of physical and social environment on the planet. Who is the master of ethno-history, gender, feminist, political, religious, Marxist, modernism, postmodernism orientalism or psycho history could have plausible answers. These various fields of history contain a historiography that could be evaluated in determining "who the mater is" in each particular discipline within each context.
