On another passs through the antiquity section of the knowledge base, I did some linking of the main antiquity page to physical geography.
For the 5th millennium BC, I have new links to human geography, to conceptual and material culture, to economics, particular religions, and social change. I added Bangladesh, which pushes Pakistan into Asia and Indonesia into Southeast Asia. I also revised the information on Pakistan just a little, but the decription of findings at one archaeological site reminds me that I need to add links to information on occupations to history and sociology.
For the 4th millennium BC, I added mostly the same links, added one to Russia, which pushes Bangladesh into Asia and Pakistan into South Asia.
For the 3rd millennium BC, I added mostly the same links, but went into specific detail on pagan religions, plus one to Nigeria, which pushes Russia into Western Civilization. I might have spent some time in the Harappan civilization, but decided to wait and do that at a later time
For the 2nd millennium BC, I had mostly the same links to add, plus one to Japan, which pushes Nigeria into African peoples.
For the early first millennium BC, I had mostly the same links to add, plus one to Mexico, which pushes Japan into Asia and Bangladesh into South Asia.
For Classical and medieval history, I added a link to Asian geography, one to occupations, and one to recreation and entertainment.
For links to early classical history, I added the same links as for the 3rd millennium BC, except for adding a link to the Philippines, which pushes Mexico into American Indians, and Brazil into South American peoples.
For links to late classical history, I added the same links as for early clasical, except for adding a link to Vietnam, which pushes the Philippines into Asia and Japan into Oriental peoples.
For links to early medieval history, I switched a little. Human geography still, and occupations, but education, since economics was already connected, and I didn't extend particular religions: I'll do that next time through. I added a link. I also added Germany, which pushed Vietnam into Asia and the Philippines into Southeast Asian peoples.
For links to to late medieval history, I did most of the same links as for Early medieval history, plus one to Egypt, which pushes Germany into Western Civilization and Russia into Northeast European peoples.
