Following the fateful decision by the late King Alfonso VII to split his kingdom in two, we meet his sons - King Sancho III of Castile and King Fernando II of Leon.

King Alfonso VII of Leon and Castile becomes seriously ill just as the Almohads begin to go on the offensive.

King Alfonso VII's attempts to conquer al-Andalus falter, causing him to search far and wide for extra troops.

At the same time as the King of Portugal is besieging Lisbon, King Alfonso VII and the Count of Barcelona are embarking on conquests of their own.

We bring the siege of Lisbon to its conclusion.

The siege of Lisbon commences, with the crusaders attacking the suburbs outside the city walls.  Construction then begins on some impressive siege equipment. 

The fleet of crusaders makes its way southwards to discuss its participation in the siege of Lisbon with King Alfonso I of Portugal.

King Alfonso I of Portugal decides to take advantage of the crusading movement for his campaign to attack Lisbon.

As Almoravid rule collapses, the Almohads arrive on the Iberian peninsula. 

We switch our focus to the southern portion of the Iberian peninsula, where Almoravid influence is waning.
