The King's English
King Henry the 5th of England has begun using English in his normal correspondence. An English King has not used English in day-to-day interactions since the Norman Conquests of the 11th century. French and Latin were the language of official correspondence, but this changed in the late 1300s when courts were required to judge cases in the language of the plaintiff. One assumes that English kings would speak English eventually but it appears that King Henry is promoting English as a political tool! He wants to legitimize his position as ruler of England by appealing to the people. His father, the Duke of Lancaster, was chosen as King because he deposed the tyrant King Richard the 2nd and saved everyone's head. (At that point Parliament would have voted him in as the Easter Bunny if that was what he wanted.) The question of the legitimacy of the Lancaster succession will spark the War of the Roses.    
Link-boys: He Can't Hold a Candle
Thou hast saved me a thousand marks in links and torches, walking with thee in the night betwixt tavern and tavern. -- Falstaff joking with Bardolph in Shakespeare's play, Henry IV, Part 1, Act III, scene 3...
What is a "link" and why does it cost money? The Middle Ages is a dark place and London is no exception. If a person wants to visit the local pub he needs a torch or lantern to light the way. In London there is a service called "link-boys" who carry a torch made of a stick covered in pitch and twisted cotton fibers (called "link"). For the cost of a farthing they will escort you from door-to-door, lighting your way. At many houses, a metal device is mounted on the wall at the doorway to snuff out the torch. However, in the winter it is difficult to find a link-boy so the Mayor of London has instituted street lamps. These lanterns will light the London streets through winter.   
The Great Schism Is Resolved
The Great Schism began when the Pope in Avignon was inspired to return to Rome for a visit and suddenly died there in 1378. The cardinals in Rome elected a new Pope but the cardinals in Avignon didn't want to move back to Rome so they elected a different Pope. This created a split in the Church called the Great Schism. The Council of Pisa was supposed to resolve the split but instead elected a third Pope! Finally, the Council of Constance was formed and by this time has either deposed, excommunicated or negotiated the resignation of the three Popes. With that accomplished they have now elected ONE POPE for the Church... Pope Martin the 5th. He is 49 years old.

(JOURNAL) quote: "I do not believe that this sudden burst of production in English after 1400 was simply a natural evolution. I think that it was encouraged by Henry IV, and even more by Henry V, as a deliberate policy intended to engage the support of Parliament and the English citizenry for a questionable usurpation of the throne. The publication of Chaucer's poems and his enshrinement as the perfecter of rhetoric in English were central to this effort. The evidence is circumstantial."

Medieval Academy of America (JOURNAL) quote: "What is clear is that the pivotal period for the use of English by the government is the reign of Henry V (1413-1422). Before Henry's reign there are few English documents among the public records; after his death Latin and French are still widely used (and continue to be for the next century), but English increasingly appears after 1422 in numerous types of writs, warrants, inquisitions, and memoranda, and in the Rotuli Parliamentorum, among the most important English official records. It is to Henry's reign, therefore, that we must first look for the beginnings of Chancery English and, in particular, to the role played by the king himself."

(JOURNAL) quote: "From the very outset, doubts were expressed about the hypothesis advanced by Fisher and Richardson, that the spread of English in the records of the central government could be directly attributed to a "language policy" put into place by the Lancastrian regime and, in particular, to the personal initiative of Henry V, who made the momentous decision-from a linguistic point of view-to have his signet letters written in English rather than French in July 1417."
