Gold is power. Focus on developing your capital county and its surrounding counties first. Build economic buildings like 'Farms and Fields' and 'Tradeports'. Use your Steward to 'Develop County' in your capital. Marry for high Stewardship spouses and assign them as your Steward. Don't be afraid to revoke titles from low-Stewardship vassals and grant them to high-Stewardship characters. High development leads to more gold, more levies, and faster innovation progress.
