Culture Changing

[Ullr]

While using Delta 1.1, i've noticed random, sometimes conflicting things with different cities with a carthage campaign, so i'd love to find some hard facts about changing culture, exactly when the switch over happens in a city and how to solve different issues.

For E.G. With Carthage, some cities switch immediately to my culture (Alexandria, the egyptian city west of it, and also cryreniaca) nothing at all needed and still had the 'factional government' built and working, yet some did all of this, with factional goverenment still intact, but won't allow any construction at all. Others (the spannish cities i believe), i had to build a colony/emporia while under 'miliatary occupation' (some even needed to have 'factional government' manually destroyed before i could build anything).

It seems the actual 'switch' of culture happens as soon as your factions colony becomes the highest or joint highest lvl colony/emporia in the city: not when the population breakdown shifts over 50% or even gets to 100%. I'd be great and anyone could confirm this. I guess this means for thalassocratic factions, i cannot realistically swap culture in land locked countries, and have to go the native controlled route, because i cant build a colony away from the sea.

As a colony/emporia is the only building that can do a lot of cultural influence, it's seems possible to actually swap over culture too early, leaving a large amount of population still not converted (giving MASSIVE unrest and possible revolt). It's happened a few times where my cityies formally swapped before i was ready to swap.

This occured mostly in land-locked (or almost land-locked) areas, as each neighbour gives a 5% culture bonus to their culture. Imagine Rome taking Toledo or Numantia in spain. With 6 neighbours giving 6x5% (30%) baba culture and a colony giving another 20% or so: 50% baba influence! Before you have even drawn even with western influence, you've got a colony too high a lvl, formally switched to western, and now your stuck with 90% unrest! Worst still, that won't change much for a while as before you can break it down you need more western influence than baba.

iv'e seen two solutions: Either flood with dilpomats (5, 6, 8 or more, giving 5% culture inf each) or a batch conversion. if you time all the local regions to 'switch' to your culture on the same turn (get the colonies to complete at the end of the same turn), with the happy bonus of millitary occupation, you'll get a massive culture influence with the neighbours feeding influence to each other. 5 turns later you should be sorted.

so look at each city carfully! A large/huge city with a lvl 2/3 foreign colony can take a while to 1) convert to local pop's and 2) finally swap over to your culture. Get the happy bonus from miliatary occupation, then flood with diplomats to tip the influence over to your culture, then wait till the population is at least half converted before formally 'switching' over with the completion of neccessary colonies/emporias.

Is there any further info about this? I'm mainly looking to find out for sure exactly when the formal switchover of culture happens, as what i've seen from most cities was deffo not the case in mediterranian egypt.

Culture change is determined by the cultural influence generated by buildings (and only those).

[Ullr]

So is that like when your factions cultural influence from buildings reaches the same percentage as the next highest other culture, on that turn the settlement becomes of your factions culture?

Exactly, when culture bonus from colony + government + other buildings is bigger than the one given by original culture the settlement culture changes.
