Feudal and Clan governments have access to the Crown Authority Law, which can be increased after researching the required [[Innovation]] and can be changed once every 20 years. Level 2 Crown Authority requires the {{iconify|Planned Assemblies}} innovation (Tribal era), while levels 3 and 4 require the {{iconify|Royal Prerogative}} innovation (Early Medieval era).
Tribal governments have access to the Tribal Authority Law and do not require Innovations to increase Tribal Authority; the law can be changed once every 10 years. The cost of changing the Authority Law scales with a Ruler's Realm Size and to a lesser extent the Ruler's {{iconify|Learning}} Skill.{{clear}}
