An important part of understanding Dharma and world religions is to understand world history. Few nations in the world have a less historical understanding of their past than India. So much of Indian history has been inadvertently or purposefully subverted by various mythologies, that the real history of India is unknown to most people (including many Indians).
The link below takes you to a page with a link to open up a Microsoft Excel file that contains 4 tabs in the spreadsheet. The tabs description is as follows (taken from the site):
1) Royal Chronology of India (Columns K through P on the right-hand side describe other civilizations - Egypt, Israel, Iraq, Iran and China). On Page 21 of this file is a Population Chart of India from 8000 B.C.E. to 2200 C.E. On Page 42 is a list of assumptions and sources used to build the timeline.
2) The History of World Religion (all major religions [Eastern AND Western] have roots in the Vedas)
3) Comparison of Most Religions
4) Festivals of India
Royal Chronology of Indian History
Though, I can't validate this information, I find it to be quite an interesting reading. Personally, I do not agree with the comparison part -- in my opinion, every religion has its own plus and minuses -- but that is a topic for another discussion.
