After going through a round of development of the late 3rd millennium BC which mostly included in pushing the interconnections among nations, my progress wasn’t too satisfying.   For Western Civilization, I finished reviewing the connections of Middle Eastern peoples, and for American Indian peoples, I have reviewed the connections of Hispanic peoples.  The squawk was when I realized that expanding most of the connections of institutions and culture to various nations as prompted by the late 3rd millennium is rather tedious and not very useful. I do better by using the centuries to push connections of later centuries to classical and medieval history, peoples of the world, and institutions.  The emphasis is likely to shift, for the next batch.
