The Old World

The Old World is the first scenario of the Francisco de Almeida campaign in Age of Empires II HD: The African Kingdoms. After the death of Henry IV of Castile, the crown went to his daughter Juana. Queen Juana married Alfonso V of Portugal, in an attempt to unite the kingdoms of Castile and Portugal. However, Queen Juana's aunt, Isabella seeks the throne of Castile for herself and her husband, Ferdinand II, King of Aragon has brought his army into Castile. The armies of Portugal and Aragon meet at the city of Toro, to decide the fate of Castile.

Allies

 * King Alfonso's Army (Portuguese): They are the soldiers of King Alfonso who are present in small groups all over the northern and eastern parts of the map. Bringing Prince Juan to them will convince them to join his army.
 * City of Toro (Spanish): They are present near the eastern edge of the map and are closer to a village than a city, as they only have a few buildings, which after defeating the initial wave of Aragonese Army (yellow), will come under the player's control. One of the player's main objectives is to defend the City of Toro but, oddly enough, even if all the buildings of Toro are destroyed, the player still won't lose.
 * Juanistas (Spanish): They have a well fortified city on the western part of the map but their city is not accessible unless the three military camps of Aragonese Army are destroyed. Once the player destroys the three camps, all of Juanistas' buildings will come under the player's control and they will surrender.
 * Castilian Villages (Spanish): They are small villages with a few buildings scattered all over the map. They don't produce any units and do not play any role at all in this scenario. They have a Hunting Wolf and a special Monk named 'Blind Lame Priest' near an Aragonese Army military camp. However, except the name and appearance, all aspects of the monk are similar to a normal Monk and if the player brings injured units to him, he will heal them. The reason as to why this special Monk is present in this scenario is unknown. They also have a Villager who will be trying to kill a sheep but there is a glitch where the sheep will not die no matter how much the Villager hits it.

Ally → Enemy

 * Isabelistas (Spanish): They have a well fortified base on the other side of the river. After all three military camps of Aragonese Army have been destroyed, they will turn their stance towards the player to enemy and start attacking the city of Juanistas which has now come under the player's control. They mainly train Archers and Light Cavalry. They also have a few Condottieros in the beginning but they cannot train more since they are not allied to an Italian player.

Enemies

 * Aragonese Army (Spanish): They have three military camps spread over the northern part of the map, along with a few villagers. They will send an initial wave to attack the player's army near the City of Toro, after which they will occasionally send Archers and Cavaliers to attack the player.
 * Aragonese Army (Spanish): They will have soldiers defending the military camps of Aragonese Army (yellow), along with a few soldiers patrolling the free area outside the camps. They have two special units - Cardinal Mendoza and Duke of Alba and killing them will give the player 500 gold each.
