My Holy Roman Empire spans Western Europe from Iceland all the way to Mali and from Portugal all the way to the Caspian Sea. My dynasty has successfully reclaimed the Kingdom of Jerusalem and held it against invading Sunni hordes while defeating Slavic incursions into Western Poland and subjugating the Norsemen in Scandinavia. Not surprisingly, the greatest threat I face are my own vassals.

Having quickly assimilated many varied cultures into the HRE, I find myself constantly shelling out gold to disgruntled kings and dukes because I can't be Irish/Anglo-Saxon/Germanic/Lombard/Greek/Arabic/African/and so on and the -16 hit combined with a constant -25 for my heir being raised by whomever can do the best (not by culture) makes it difficult to make any progress financially.

The best way to fix this is to raise my Tolerance level in the Cultural Research track. However, even with my capital in Constantinople and 3 cities with maxed out universities, my spymaster grabbing research points in Damascus, and my chaplain hitting the books like crazy, I still only manage a meager 1.25 points per month.

Is there some way to speed things up a bit? It would be a lot easier to take all of Northern Africa and tackle Russia if I don't have to worry about hemorrhaging gold to my vassals.

In addition to JMR's answer:

If you have the Way of Life DLC, you could take the Scholarship Focus and use the Decision to Build an Observatory. Choosing to study "what weirdness is out there" will grant you a total of 130 Cultural tech points (with an option of an extra 200 if you feel like buying the Necronomicon) over the course of about 5 years. This option also boosts your Learning stat in several ways, which will improve the standard research trickle.

  • Thanks, J! I was going to purchase that DLC next month. Maybe I should get it sooner! Commented May 30, 2015 at 20:08

    After installing the Way of Life DLC (which helped tons, thanks CrusaderJ), I continued to fool around with how to get rid of the annoying Foreigner negative modifier. I found that if you can educate the heir of the ruler in question under someone of your culture, you can change them to your culture and gradually eliminate that problem. It takes a couple of generations, though, to fully cement your culture in a dynastic line. Commented Jul 2, 2015 at 15:57

What are your character's learning and diplomacy stats? These have a large impact on the research point generation of your realm. From the wiki, the formula is:

Monthly points = (0.04 *(Learning + Skill) * RankBonus) + BuildingBonus

Besides a direct bonus for learning skill, the "skill" modifier here is either your martial, diplomatic, or stewardship skill, with each increasing your rate for military, cultural, and economic techs respectively. "Rank bonus" is, as the name suggests, the rank of the character. As an emperor, for you this is 1.4. Building bonus is self explanatory as well, its the bonus from tech boosting buildings.

So besides building more tech buildings, you can boost your cultural tech research rate by improving your character's diplomatic and learning skill stats.

  • The character stats vary from ruler to ruler. Though I try to emphasize Diplomacy and Learning in selection of my heir's guardian/mentor, all too often, I find my choices limited. I was hoping for something external to my character that would help, something I may have missed. Commented May 29, 2015 at 11:50
