While the _general post_ dates from the Stuarts, the establishment of a regular _riding post_ in England owes its origin to Edward IV. The English post seems from the first to have been fully commensurate with the demands for its service, its growth depending on the gradual advance which the country made in other measures of social progress. Four or five centuries ago, few private persons could either read or write. On the other hand, the business of the State demanded correspondence. The king had his barons to summon, or his sheriffs to instruct, and letters of writ were issued accordingly, a few Government messengers supplying all the wants of the time. Now and then the nobles would require to address each other, and sometimes to correspond with their dependents, but, as a general rule, neither the serf nor his master had the power, even if they had the will, to engage much in writing. As time wore on, and we come nearer the age of the Tudors, the desire for learning spread, though still the few who engaged in literary or scientific pursuits were either attached to the Court or to the monastic establishments. Even when the Tudor dynasty came in, trade with foreign countries, and remote districts in our own country, was almost equally unknown. Each district dwelt alone, supplied its own wants, and evinced very little desire for any closer communication. In the earliest times in England, and prior to the first regular horse posts, both public and private letters were sent by private messengers, travelling when required. In the reign of Henry I. messengers were first permanently employed by the king. So early as the reign of King John the payments to _Nuncii_--as these messengers were now called--for the conveyance of Government despatches, are to be found entered in the _Close_ and _Misæ Rolls_, "and the entries of these payments may be traced in an almost unbroken series through the records of many subsequent reigns." Nuncii were also attached to the establishments of the principal barons of the time, and communications passed between them by means of those functionaries. In the reign of Henry III., the son and successor of King John, these messengers began to wear the royal livery. At first it was necessary for them to keep horses of their own, or use those belonging to the royal or baronial mansion. In the reign of Edward I. we find that fixed stations or _posts_ were established, at which places horses were kept for hire, the _Nuncii_ ceasing to provide horses of their own, or borrowing from private individuals. Several private letters are in existence, dating as far back as the reign of Edward II., which bear the appearance of having been carried by the _Nuncii_ of that period, with "Haste, post, haste!" written on the backs of them.
