"Ultima ratio regum." — Motto on French cannon cast by Louis XIV

Military Research Military is one of four technology disciplines available at the Library. It increases the population limit and unlocks new units and military technologies.

Benefits Edit

Like all Library research, Military research has a total of 7 levels to research. Each level researched...

  • increases the Population Limit by +25, up to a maximum of 200.
  • unlocks all military units of the same age.
  • reduces production cost for units of previous ages by 5% per level ahead
  • reduces upgrade cost for units of previous ages by 10% per level ahead

Researching Military technology also unlocks all military structures (except Docks) as well as Fort technologies:

Military Technology Research cost Required for
1 The Art of War 120 Food Barracks, Tower, Stable
2 Mercenaries 100 Food / 100 Metal Siege Factory, Fort, Keep, Castle, Airbase, Missile Silo
3 Standing Army 160 Knowledge / 200 Metal Fort technologies level 1
4 Conscription 360 Knowledge / 250 Metal Stockade, Fortress, Fort technologies level 2
5 Levee en Masse 650 Knowledge / 400 Metal
6 Nation-in-Arms 1300 Knowledge / 500 Metal Bunker, Redoubt, Fort technologies level 3
7 Selective Service 1800 Knowledge / 1200 Metal

Note that research cost also depends on the current level of Science Science research as well as any cost modifiers from nation powers and rare resources.

Miscellaneous Edit


Connecting Furs reduces Military research cost by 25%.

  • Connect the Furs rare resource with a Merchant to reduce Military research cost by 25%. This does not affect the "red" future technology Missile Shield.
  • The Greeks receive a general 10% discount on all Library research cost (except for Knowledge) and research technologies 100% faster.
  • The Romans and the Aztecs start with the first Military technology already researched (unless playing a Nomad or City Center Only game).
  • The Bantu receive +50 to their Population Limit per level researched. They also do not require Military technology to unlock new units. However, unit and upgrade cost are increased by 10% per age behind in military research.
