The stereotype of the Vlachs of Albania was the personification of the shepherd. In fact, they also performed other exclusive functions such as caravan leaders and couriers. Professor Pëllumb Xhufi, at the international scientific conference on the topic “Vlachs of Albania in the Balkan context”, said that sources from the 15th century onwards call the couriers who delivered urgent mail and messages from Istanbul with the term ulak.

"Marin Barletit stops at this category of service. He cites a case when, during the siege of Berat by Skanderbeg's forces in 1455, the sultan sent an urgent message to Gjirokastra that the Vlach couriers brought at the speed of the wind. From Istanbul to Gjirokastra they brought it in 3 days, but this journey usually took 1 month. This, says Barleti, is because the sultan had issued an order according to which the Vlach couriers could ask anyone they met on the road to change horses, so they came quickly," said Xhufi.

The conference brought to attention various features of this coexistence, along with their displacements, from the highlands of Opar, Voskopoja, Kolonja, Këlcyra towards Myzeqe, another possession of the Muzakaj. For Ferit Duka, in the case of Voskopoja, however, it must be understood that the Ottoman registers record their arrival.

"Ottoman documents show that the majority of the Voskopoja population was indigenous, historical inhabitants of this village. When there were newcomers, they were registered with their names and the name of origin, as happened with the meçovites of Voskopoja," said the Duke.

Various researchers focused on different aspects of the life of the Vlachs, as humanists, philanthropists and artists, their contribution to the sovereignty of Albania, but also their role in Greece and beyond.
