History Channel - The Crusaders (2019)

These are the REAL stories of the medieval Knights who dedicated their entire lives to God and to the fight against His enemies…the men of the Holy Orders …The CRUSADERS.
Spanning most of the High Middle Ages (1050-1300 CE), a series of military expeditions called the Crusades was launched from Christian Europe against the peoples of the Near East. The Crusades were military campaigns organised by popes and Christian western powers to take Jerusalem and the Holy Land back from Muslim control and then defend those gains.
With a cry of "God wills it!" medieval knights ushered in a new era in European history. Across Europe a wave of pious enthusiasm led many thousands to leave their homes, family, and friends to march to distant lands in a great struggle for Christ.

Part 1: The Knights Templar
The Poor Fellow-Soldiers of Christ and of the Temple of Solomon are known to history as the Knights Templar. They were among the most wealthy and powerful of all of the western military orders and for the 200 hundred years of their existence, were at the forefront of Christian finance.
A look at the wealthiest of all the western military orders. Endorsed by the Catholic Church around 1129, these are Templar knights, and this is their story. If any single image epitomises the medieval era in the popular imagination, it is that of the heroic, chivalrous Knight. Clad in shining armour, his story was first told by authors in the 19th century before being carried on by Hollywood. But what are the truths behind the myths and legends? The Crusaders aims to find out.

Part 2: The Teutonic Knights
The Teutonic Knights were one of the great chivalric orders that emerged from the Crusades, alongside the Hospitallers and Templars. The Teutonic Knights evolved out of a "fraternity" of German crusaders who took part in the siege of Acre during the Third Crusade.
'Help, defend, Heal' was the motto of the 'Order of Brothers of the German House of Saint Mary in Jerusalem', the Teutonic Order. It was formed to aid Christians on their pilgrimages to the Holy Land and to establish hospitals.

Part 3: The Knights Hospitallers
The Knights of Lazarus were originally founded at a leper hospital around 1098 by the Crusaders of the Latin Kingdom of Jerusalem. It was established to treat the disease, because the Knights were lepers themselves.
Once called "The Hospitallers" The Knights of St John were founded to provide care for the poor, sick or injured pilgrims on their journey to the Holy Land. They evolved into a military order with it's own Papal Charter.
