Hugh Trevor-Roper in the context of "Adam Sisman"

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.

The Protestant work ethic, also known as the Calvinist work ethic or the Puritan work ethic, is a work ethic concept in sociology, economics, and history. It emphasizes that a person's subscription to the values espoused by the Protestant faith, particularly Calvinism, results in diligence, discipline, and frugality. In 1905, sociologist Max Weber initially coined the phrase in his book The Protestant Ethic and the Spirit of Capitalism. Weber asserted that Protestant ethics and values, along with the Calvinist doctrines of asceticism and predestination, enabled the rise and spread of capitalism. Just as priests and caring professionals are deemed to have a vocation (or "calling" from God) for their work, according to the Protestant work ethic the "lowly" workman also has a noble vocation which he can fulfill through dedication to his work.

However, despite Weber's book being one of the most influential and cited in sociology, the thesis presented has been controversial since its release. In opposition to Weber, historians such as Fernand Braudel and Hugh Trevor-Roper assert that the Protestant work ethic did not create capitalism, and that capitalism developed in pre-Reformation Catholic communities. Historian Laurence R. Iannaccone has written that "the most noteworthy feature of the Protestant Ethic thesis is its absence of empirical support." The concept often helps define the self-view of societies of Northern, Central and Northwestern Europe and the United States.
