The Most Illustrious Order of St. Patrick

In honor of St. Patrick's Day, I've decided to write about the Most Illustrious Order of St. Patrick. This is the Wikipedia article:
The Most Illustrious Order of Saint Patrick is an order of chivalry associated with Ireland. The Order was created in 1783 by George III. The regular creation of knighthoods of St Patrick lasted until 1922, when most of Ireland became independent as the Irish Free State. While the Order technically still exists, no knighthood of St Patrick has been created since 1934, and the last surviving knight, Prince Henry, Duke of Gloucester, died in 1974. The Queen however remains the Sovereign of the Order, and one officer, Ulster King of Arms, who is now Norroy and Ulster King of Arms, also survives. The patron saint of the Order is St Patrick. Its motto is Quis separabit?, or Latin for "Who will separate us?"; an allusion to the Vulgate translation of Romans 8:35, "Who shall separate us from the love of Christ?"
Most British orders of chivalry cover the entire kingdom, but the three most exalted ones each pertain to one constituent nation only. The Order of St Patrick, which pertains to Ireland, is the third-most senior in precedence and age. Its equivalent in England, The Most Noble Order of the Garter, is the oldest documented order of chivalry in the United Kingdom, dating to the middle fourteenth century. The Scottish equivalent is The Most Ancient and Most Noble Order of the Thistle, dating in its modern form to 1687.
The Order of St Patrick earned international coverage when in 1907 its insignia, known generally as the Irish Crown Jewels, were stolen from Dublin Castle shortly before a visit by the Order's Sovereign, King Edward VII. Their whereabouts remain a mystery.
