I consider it as AoE 3 revolutions (playable micro-civs but starting from base civs)
The Sultan’s Army: it is Saladin’s Army (in AoE 2 remember the phrase, where are you going with that army, Saladin?) (1174-1193)
Jade Empire: It is based on the mythology of Tang and Song China (618-1279)…
Order of the Dragon: It is the Order of Emperor Sigismund who fought against the Hussites and the Ottomans (1408-1529)
Joan of Arc: The army of Joan of Arc (1429-1431)
