The Maltese cross has become an iconic part of the country of Malta's heritage and culture over the course of hundreds of years. Most commonly associated with the Knights of Malta, the symbol is now used on everything from coins to the logo of different organizations and institutions internationally. The origin of the cross is debated, although one common thought is that it evolved from a cross typically found on coins minted in the Italian Republic, Amalfi, during the 11th century. It was officially adopted by the Knights Hospitallers of St. John in 1126, and stylistically its origins point to the crosses used in the crusades, known to those then as the symbol of the "Christian Warrior." It is said that the points on the cross denote the eight aspirations and obligations of the knights, "to live in truth, have faith, repent one's sins, give proof of humility, love justice, be merciful, be sincere and wholehearted, and to endure persecution." To this day, the Maltese cross remains the symbol of the Sovereign Military Order of Malta, an international organization dedicated to medical and humanitarian aid.
