One of some versions of the name Pasinler - it is derived from the ancient tribe called Phasians (Phazians).

The name of this tribe seems to have survived in latter-day regional toponyms – Armenian Basean, Greek Phasiane, Georgian Basiani,[7] and Turkish Pasin.

In the story of the Armenian chronicler Favstos Buzand (5th century), the thief of the Orduni clan attacked the power of King Khosrov III, seizing and destroying the royal house, as a result of which the princes of the Orduni clan were killed by order of Khosrov.

However, after formation of the Georgian Kingdom, Bagrat’s son George I inherited a longstanding claim to David's succession.

While Basil was preoccupied with his Bulgarian campaigns, George gained momentum to invade Tayk/Tao and Basean/Basiani in 1014, which caused unsuccessful Byzantine-Georgian wars.

The province was part of the united Kingdom of Georgia as an ordinary duchy till 1545, when Basiani was conquered by the Ottoman Empire.

When World War broke out the Russians advanced to the plain of Pasinler but quickly retreated together with many of the local Armenian population, some 4,000 remained and were deported.
