Are there any cities that fell out of prominence in ancient times, but definitely could have retained prominence into the modern era? Or locations that didn't host strategic or capital cities historically, which definitely could have?
- Hattusa (Had 50,000 people in the Bronze Age. Fell with the Hittite Empire)
- Nineveh (Had almost 250,000 people. Fell with the Assyrian Empire, and may or may not have been resettled later)
- Memphis, Egypt (Could have remained the premier city of Egypt without the construction of Alexandria. Pretty close to Cairo and Fustat, so had potential in later eras)
- "Little Egypt" in Southern Illinois, at the confluence of the Missisisippi and Ohio Rivers, definitely could have become a highly populated center.
