Innovation 	Region 	Cultures 	Effect	Description
Consolidation of Soissons	Western Europe 	Greco-Roman Heritage, Soissonian 	
*Can recruit Soissonian Auxiliaries as Men-at-Arms
*Can recruit Soissonian Legionaries as Men-at-Arms
*Grants access to regular Men-at-Arms units. Existing regiments can now be modified.
*Levy Size: -50%
*Holding Taxes: -5%	The Consolidation of Soissons refers to a specific time period when the Kingdom of Soissons (in Roman, Regnum Suessionum) consolidated its hold over its territory by adapting to the new normal. The rise of many nations in Western Europe had resulted in the abandonment of most of the Roman bureaucratic system in favor of a landed aristocracy formed from the various centurions, legates and senators. In spite of this, the Soissonian senate still remain to implement new policies of the time. As a result, Soissons was in essence a feudal state with elements of the old Roman bureaucracy.
The one thing that affected more was Soissons' army, a late Roman army in Soissons which has since then been landed. In an effort to defend its territory, Soissonians were provided weapons and armor to fortify their homes while the legionary army is being reformed. After surviving for a century and a half, it was ultimately decided the legionary army would be landed, and the first Soissonian aristocracy was formed from the legates, centurions and senators while the legionaries would receive land. This would put the Soissonian legionary officers into declaring fealty to the king of Soissons in exchange for military service.
Consolidation of Palmyra 	Middle East 	Greco-Roman Heritage, Palmyrene 	
*Can recruit Palmyrene Auxiliaries
*Can recruit Palmyrene Legionaries as Men-at-Arms
*Can recruit Camel Riders as Men-at-Arms
*Grants access to regular Men-at-Arms units. Existing regiments can now be modified.
*+8 Size of Men-at-Arms Regiments
*+2 Max number of Men-at-Arms Regiments	The Consolidation of Palmyra refers to a specific time period when the Palmyrene Empire/Kingdom consolidated its hold over its territory by adapting to the new normal. The rise of many nations in the Middle East and Persia had resulted in the adoption of a Palmyrenic bureaucracy adapted from the original Roman bureaucratic system albeit laced with elements of Western European feudal principles, a great departure from its sub-Roman government. Despite this, a Palmyrene aristocracy would be empowered and would be involved in the imperial bureaucracy.
Consolidation of Atlantis	North Atlantic, Atlantis	Atlantean, Greco-Atlantean, Greek, Kalaidian
