Knights of Malta celebrate their 100th birthday at the Vatican

February 9, 2013, marked the 900th birthday of the founding of the Knights of Malta, a Roman Catholic religious order noted for its charitable works. The group celebrated its birthday with a parade around St. Peter's Square and a visit with Pope Benedict XVI, who is himself a member of the Knights.

Although they claim no territory, the Knights of Malta enjoy many of the privileges normally given to sovereign nations, including the printing of their own money and postage as well as diplomatic relations with over 100 countries.
