It was the "whites". They are the people of "Knights Templar" who allied with the Western European Christian kingdoms from the ancient German (Holy Roman Empire), Italy (Papal Kingdom), French (Frankish), Spanish (Iberian Peninsula or Aragon), and England (Britons) to against the Islamic Saracen troops and conquered the "Holy Land of Jerusalem" (Today is Palestine) and did the "Crusade War" for hundreds of years, 4 times longtime war.

The Temple as Bankers
The Templars quite early on their history developed a reputation for being reliable bankers. They were - in effect - Europe's first bank.

Monies thus deposited proved to be quite safe, as Templar keeps were formidable buildings. Some of their castles in Outremer, for instance, were so well defended.

The Structure of the Order
As the Temple grew from being the original nine soldier- monks sworn to poverty, chastity and obedience into what we would nowadays recognise multinational corporation, so too did the structure of the Order evolve to reflect and support its expanding role in affairs of the crusader states.
