Here's the final five of my ideas that I have thought of (not totally done)
Colombian Empire (Gran Colombia)
Leader: Simon Bolivar
Agenda: El Liberator- Dislikes civilizations that occupy other cities or city states from another continent. Likes civilizations that help liberate them.
LA: Admirable Campaign +25% Combat strength when attacking an occupied city. No warmongering penalties for keeping the city after.
UA: Revolutionary State- Pay less gold to unlock civic and government changes. Does not go into anarchy when switching governments.
UU: Llanero
UB: Lancero (Replaces Military Academy) Not exactly from Gran Colombia, but modern day Colombia.
Ethiopian Empire (Ethiopia) Although an Axum leader
Leader: Ezana
Agenda: Religious State- Likes all of his cities to be under one religion. Dislikes civilizations that have different religions in their cities.
LA: Ezana Stone- Combat strength against other civilizations if a majority of cities follows your religion.
UA: Adwa - Combat bonus when fighting a unit at least one era ahead.
UU: Mehal Sefari Melee unit that unlocks at rifling.
UB: Stele (replaces monuments) provides faith as well as culture
Swedish Empire (Sweden)
Leader: Gustavus Adolphus
Agenda: Stormasktisden- Likes civilizations who have a large standing diverse army with at least one corp or army in later eras.
LA: Father of Modern Warfare- Can turn land units into corps earlier. Support units may move faster being escorted. Bombard units have extra movement.
UA: Nobel Prizes- +5 Points per great person of each district type in a city you are the suzerain of.
UU: Karoliner( replaces Musketman)
UB: Furniture Warehouse (Replaces workshop) There probably is a better one, but I can just think of IKEA.
Austrian Empire (Austria)
Leader: Maria Theresa
Agenda: Marriage Proposals-Likes to send envoys to every city-state and delegates to every civ she meets. Dislikes civilizations that has an envoy to a city-state, or a delegation(embassy) to a civilization she doesn’t have .
LA: Hapsburg-Lorraine House- Has an extra Diplomatic Policy Spot. Gains 1 more influence point per turn.
UA: Archduchy- Can't think of what it could do.
UU: Grenzer (Replaces Musketman)
UI: Opera House (replaces the Ampitheater) +2 Writing, +2 Music Slots at Opera and Ballet.
Italian Empire (Italy) Two Leaders
UA: Piazza Duomo- Tourism is doubled for Holy Sites, and Wonders when Adjacent to City Center.
UU: Condotierri (with Mercenaries) More combat strength for each different land unit adjacent to it.
UI: Galleria– (replaces art museum) one more great work of Art Slot and automatically themed when complete.
Leader: Lorenzo de Medici (Capital: Florence)
Agenda: Medici Bank- Likes to spend much gold but not go bankrupt. Dislikes civilizations that do not use gold wisely by going bankrupt or not spending at all.
LA: Master of Florence- 25% discount on purchasing great people with gold. Commercial Hub buildings provide more gold.
Leader: Guglielmo Embriaco (Capital: Genoa)
Agenda: Crusader State- Likes to protect city-states from attacks from other civilizations. Dislikes civilizations going to war with city-states.
LA: Military Merchant- Naval Units support to adjacent land units. Gold for every city-state you are the suzerain of. Can train Genoese Crossbowmen.
