The original international military orders were the Order of the Holy Sepulchre, the Knights Hospitaller, the Knights Templar, the Order of Saint Lazarus, and the Teutonic Knights.

Knights of the Holy Sepulchre -

In 1113, after their recognition by Pope Paschal II as a military branch, Militi Sancti Sepulcri, the Knights of the Holy Sepulchre, allied themselves with the Canons of the Holy Sepulchre. The Militi Sancti Sepulcri were charged with securing the defense of the sacred site and to protect pilgrims visiting the Holy Land.

Together, the canons and the Militi Sancti Sepulcri formed part of the structure of which evolved into the modern Equestrian Order of the Holy Sepulchre of Jerusalem. Today the order, whose primary mission is to "support the Christian presence in the Holy Land," has an estimated 30,000 knights and dames in 60 regions around the world.

Headquartered first in Jerusalem until 1291, the order later relocated to the island of Rhodes. After coming under siege by Ottoman Janissaries in December 1522 (pictured), the order was again forced to move, this time to Malta, where it maintained a presence from 1530 to 1798. Its final home was Saint Petersburg, Russia, from 1799 to 1801.

The red cross -

Distinguished by their white mantles with a red cross, Templar knights were among the most skilled fighting units of the Crusades. But the Templars also became a favored charity throughout Christendom and grew rapidly in membership and power. Pictured is a flag used by Templars in battle.

Non-combatant members of the order, who made up as much as 90% of their members, managed a large economic infrastructure throughout Christendom. In fact, the order is credited in developing innovative financial techniques that were an early form of banking.

Decline and dissolution -

By the mid-12th century, it was clear that Muslim forces were gaining the upper hand over the Crusaders. When the Holy Land was finally lost, support for the Knights Templar faded. Pope Clement V disbanded the order in 1312, under pressure from King Philip IV of France. Thousands of Templar members were rounded up, tortured into giving false confessions, and burned at the stake.

Order of Christ -

Out of the ashes rose the Order of Christ. Reconstituted in Portugal after the abolition of the Templars, the order was founded in 1319, with the protection of the Portuguese king, Dom Dinis I. Today, the Military Order of Christ is an Honorific Order conferred for outstanding services to the Portuguese Republic on military officers, civilians, and other public authorities. The Convent of Christ (pictured), the former 12th-century Templar stronghold that became the headquarters of the renamed Order of Christ, is located in Tomar and is a popular visitor attraction.

After the fall of Jerusalem, the order split in two main branches in Italy and in France: the Order of Saint Lazarus in Italy was merged with the Order of Saint Maurice in France. Emmanuel Philibert (pictured) became founder and first Grand Master of the amalgamated Order of Saints Maurice and Lazarus, recognized in 1572 by Pope Gregory XIII.

Order of Saints Maurice and Lazarus -

During the French Revolution (1789–1799) a 1791 decree suppressed all royal and knightly orders in France. Another decree the following year confiscated all the order's properties. By 1830 the French branch ceased to exist. However, the Italian branch of the Order of Saints Maurice and Lazarus continued to function, and today has around 2,000 members worldwide.

State of the Teutonic Order -

It was in the 13th century during the Northern Crusades along the Baltic Sea that the order created the State of the Teutonic Order. Its territory was in the modern countries of Estonia, Latvia, Lithuania, Germany, Poland, Russia, and Sweden (Gotland). However, following its defeat to forces of the Crown of the Kingdom of Poland and the Grand Duchy of Lithuania at the Battle of Grunwald in 1410 (pictured), the Teutonic Order fell into decline.

Malbork Castle, Poland -

The military history of the Teutonic Knights ended in 1805 with the disbursal of the order's territory by Napoleon Bonaparte to his German allies in 1810 after the signing of the Treaty of Schönbrunn between France and Austria. Today, visitors and historians alike can marvel at the splendor of Malbork Castle in Poland, the Teutonic Order's 13th-century headquarters.
