The regular Imperial posts were established towards the end of the fifteenth century by the Emperor Maximilian I. Johann von Taxis was the first Imperial Postmaster, and the earliest record of his tenure of the office is in 1489.[706] A decree suppressing the system of _Boten-Anstalten_ and the _Metzgerposten_ was issued, but these posts continued, and it was discovered at a later date that their continuance was not incompatible with the maintenance of a system of Imperial posts.[707] The Imperial posts were to provide more particularly for the transmission of despatches, and their immediate object was to provide a means of obtaining information regarding the Turks, and a means of communication with the princes of neighbouring territories.[708] Their history is inseparable from that of the family of Thurn and Taxis, to whom their management was from the first entrusted. This family was of Italian origin, and before the establishment of the Imperial posts, Roger the First of Thurn and Taxis had established a horse-post between Italy and the Tyrol, which proved of so much value to the Empire that as a reward Roger was made a chevalier. On the routes along which the Imperial posts were laid, stages were fixed at intervals of about 5 (German) miles, and messengers were stationed at each stage.[709] These messengers from the first enjoyed the privilege of exemption from all taxes and charges in all the countries through which the post routes passed. The posts were solely for the service of the Emperor, and at his charge; and at first, like the earlier messenger services, were established temporarily for special purposes, such as the movements of the Imperial Court, or to meet necessities arising from war; or permanently to provide services between distant and newly acquired territory.[710] In 1500 Francis von Taxis was appointed _capitaine et maître de nos postes_ at Ghent by Philip the Fair, son of the Emperor Maximilian I, and in 1505 a convention was concluded between Philip and von Taxis under which the latter undertook to establish a line of posts between the Court of Maximilian I, the Court of the French King, and the Spanish Court, for a payment of 12,000 livres a year. The German and Spanish services were intended to maintain permanent and regular communications. The French post was intended to facilitate diplomatic intercourse.[711] The time occupied in the transmission of letters between Innsbruck and Brussels at this period was 5-1/2 days in summer and 6-1/2 days in winter; between Paris and Brussels 44 hours; and between Granada and Brussels 15 days.
