Although I have a general idea of 20th century world history, the meat is in the details. I’ve been going through the 5 year periods, adding a nation at time, and adding a sentence or two to summarize the most outstanding events of that period in that nation. As I add more nations, the major peoples begin to emerge, and then some of the largest nations. This way, a summary of the prominent events of the world gradually begins to emerge. Although this process is slow and tedious, since I am making links from the historical periods to numerous other subjects at the same time, I am pleased with the summaries that it is beginning to produce. At present, I am working through the 1980s.
