Most of the development of this period was actually done by examining in earlier periods. Western Civilization began to take shape in this period. 

I've finally finished going through a review of the aids to classical and medieval history.  There wasn't a great deal of visible improvement, 

This was an excessivly dry period to work through.  Although there were quite a few developments, many of them were in areas of the world that haven't been examined in sufficient detail. The connections to later periods of history are now continuous but not well developed. From this period on, I will be able to consider Latin peoples, which means that I can do some development of the Roman republic and empire. 

The New Kingdom of Egypt, early Persian kingdoms, and the iron age Vedic peoples of India, and the Chinese Shang and Zhou dynasties were notable as major civilizations of this period. 

By using this as motivation for examination of the 19th and 20th century, I now have a glimmer of how these connections will become useful. In the 19th and 20th century, as Western colonial empires reached their height and were disbanded with decolonization movements, World history became less Eurocentric and histories of other peoples were researched and developed. Developing this idea will take more time.

Western Civilization was not been developed much, although I have space for Germanic and Northeast European peoples, and connections to social institutions are progressing rapidly. I have a few odd and unexpected advances  such as Germanic peoples now properly including Germany. There has also been more development of Japan, Mexico, and the Philippines, and Japan now properly includes Tokyo.  

Religion, government, culture, and anthropology are being developed mostly by connecting more nations.

One again, the chief value in attempting to apply other history was the incentive to develop more of the 19th and 20th century. This may actually be more useful by then next time I work back through this period. Nations and people of the world are mostly being used to examine details of social structure and change, and vice versa. So far, developments among the major civilizaions in the Middle East, South Asia, and China are the most apparent. The connections to institutions are improving, and more details of religion and government can be examined. The links to culture are also improving, and I am have begun doing a little in anthropology.
