CIVILIZATION_MER_AUSTRIA, AD 976
CIVILIZATION_CVS_SONGHAI, AD 1464

Thanks, I'll include these, send more if you like

CIVILIZATION_JFD_USSR, AD 1917

Added all of these to the latest update in ModSupport.sql

CIVILIZATION_JFD_ITALY, AD 1861

CIVILIZATION_JFD_PORTUGAL, AD 1143
CIVILIZATION_JFD_PAPAL_STATES, AD 754

CIVILIZATION_CJL_BABYLON, BC 3960

Thanks, I'll use these in the next update. I'll probably add another list of spawn dates for true historical starts, which will be when a Civ as a nation was founded, to the exact year. I'm sure this is what a lot of people wanted in the first place. I don't think it balances that well honestly, and of course you can debate whether a Civ represents a nation state or not, but I'll leave that for the player to decide.

('CIVILIZATION_GEDEMO_HUNNIC', 370)

This mod has it's own support build in already, but I think it would be better if it was all in one place, if the data in historical spawn dates would override it.

Merrick's Anglo-Saxons

CIVILIZATION_GEDEMO_VIETNAM, BC 207

CIVILIZATION_SAILOR_NORTH_POLE, AD270 (Saint Nicholas's Birth year)

I've been playing with Gedemo's city states for a while and I had just edited all these into the mod file for myself. Some city states have an accurate start dtae, others are just approximated from a few dozen years before they were first mentioned.
