The story
The post in the Romanian provinces is known since the Middle Ages. It was created from the need to spread the sovereigns’ orders up to the limits of the territory they owned. Sovereigns’ couriers used horses, dutifully given to them by the inhabitants of the transited villages and towns.
The first document attesting the existence of postal services in Romanian-speaking lands was "The Charter" issued by Sovereign Mircea the Elder, in 1399, at Giurgiu. By this, localities were required to provide the royal couriers with transportation means, horses and two wheels carts, named remount.
At the beginning, the post was mainly based on the transportation of travellers and official mail of the high seniors and sovereigns. After 1850, in the administrative cities, the urban postal stations were converted into post offices. At that time, there were 30 postal routes, with postal stations, having Craiova as joint centre. In 1852, the mail service for private individuals was organized, under the supervision of the Ministry of Finances.
On July 23, 1862, the 527 Decree was issued regarding the unification of the postal administrations of Moldavia and Wallachia, starting with August 1, 1862. Following the unification, the general directorate management is entrusted to Panait Sevescu, who had also been managing Muntenia branch since December 1860.
