Allied powers of World War II in the context of "Second Polish Republic"

The historiography of World War II is the study of how historians portray the causes, conduct, and outcomes of World War II.

There are different perspectives on the causes of the war; the three most prominent are the Orthodox from the 1950s, Revisionist from the 1970s, and Post-Revisionism which offers the most contemporary perspective. The orthodox perspective arose during the aftermath of the war. The main historian noted for this perspective is Hugh Trevor-Roper. Orthodox historians argue that Hitler was a master planner who intentionally started World War II due to his strong beliefs on fascism, expansionism, and the supremacy of the German state. Revisionist historians argue that it was an ordinary war by world standards and that Hitler was an opportunist of the sort who commonly appears in world history; he merely took advantage of the opportunities given to him. This viewpoint became popular in the 1970s, especially in the revisionism of A. J. P. Taylor. Orthodox historians argue that, throughout the course of the war, the Axis powers were an evil consuming the world with their powerful message and malignant ideology, while the Allied powers were trying to protect democracy and freedom. Post-revisionist historians of the causes, such as Alan Bullock, argue that the cause of the war was a matter of both the evil and the banal. Essentially Hitler was a strategist with clear aims and objectives, that would not have been achievable without taking advantage of the opportunities given to him. Each perspective of World War II offers a different analysis and provides different perspectives on the blame, conduct and causes of the war.
