The Charlotte Mason approach to history begins with the history of the home country and moves outward. By the high school years, United States history, which has, in all likelihood, received the most attention in elementary and middle school years, will cede space to other parts of the world. United States history will venture into more obscure moments at the same time that it provides a familiar reference point for the study of other national histories.
How far out from American history one moves depends on one’s commitment to exploring the geographical fullness of history (it takes effort) and on the availability of quality materials that are living and accurate, free of a progressive agenda and compatible with the Catholic faith. The latter is a serious limitation.
Each stream for high school will take a global approach, but, at the same time, will keep national and regional histories intact, so that those threads are easier to follow. Modern history will begin with the United States, then proceed to England, France, Spain, Central Europe, Eastern Europe, Italy, and then Asia, from West to East. Individual students can spend more time with regions and/or countries in which there is either a personal or familial interest; but, time imposes real limits, and priorities must be set.
