Age of Empires Series Wiki

First Crusade is a technology in Age of Empires II: Definitive Edition - Lords of the West that is unique to the Sicilians and available at the Castle. Once researched, it lets up to 5 Town Centers each spawn a one-time group of 7 Serjeants. Additionally, it makes all Sicilian units more resistant to conversion (having the same effect as the Monastery technology Faith).

First Crusade is not already researched in Imperial or Post-Imperial matches (like Flemish Revolution).


The First Crusade research is an easy way to get a lot of infantry units very fast. Its effect is maximized after a build using tons of Town Centers. It may allow some greedier strategies like a four or five Town Center boom on a map like Arena. It is a rather expensive technology which takes a lot of time to research though.

In some circumstances, First Crusade may act as a panic button if the player needs to defend against an invasion but does not have enough troops near their Town Centers. One thing to note is that this technology can still be researched and will provide the same number of units even if it results in the player exceeding maximum population.

If the player has 5 Town Centers, each Serjeant delivered by First Crusade will cost approximately 8.6 food and 17.1 gold. Also, researching the technology takes the same time as training 5 Serjeants in a Castle, and so it is always recommended to research it, both cost-wise and time-wise, whenever the player wants to have a big army of Serjeants.

While not the most famous in the First Crusade in 1091, Sicily, like many other European entities, experienced the effect of the Crusades as military religious orders set themselves up in Sicily, like the Templars, Hospitallers, and the Teutonic Knights. Their famous battles were the Battle of Dorylaeum and Siege of Antioch. However, the multi-ethnic state of Sicily kept them from actively participating in the religious conflicts, serving mainly to provide material services to the organizations.

Two Italo-Norman nobles, Tancred and Bohemond I of Antioch were amongst the leaders of the First Crusade and founded principalities in Galilee and Antioch.


  • If allied with a Teuton player, the Sicilians have the best conversion resistance in the game after researching both First Crusade and Faith.
  • The feature of spawning a group of military units for existing buildings is similar to the effect of a few Home City Cards, such as the Strelet Horde of the Russians and the Allotment System of the Swedes, as well as the Clan Offerings technology from Japanese Isolation of the Japanese in Age of Empires III.
  • Once researched by a player, all other players in the game receive a message: <player name> has called a Crusade against the enemy -- Serjeants flock to their cause!
