[citation needed] Horasan is also one of the spellings of the Khorasan (or Greater Khorasan), which is a region in north east Iran with historical importance, and it is also the source of the name of the town as the first settlers of the town migrated from this region.

It appears that the first traces of civilization in the district having remains of the Bronze Age point to the place's history from the year of 4000 B.C.

Holding a strategic role in the East–West connection via the Silk Road, the location of Horasan is home to ancient settlements and was a scene to early civil advancements.

Various Turkic peoples under Göktürk and Hunnic rule, as well as the Mogols, immigrated to Horasan after the invasions of the Arabs and Genghis Khan.

In following years, the land saw Roman, Assyrian, Urartu, Median and Persian, Sasani, Arabic and Byzantine invasions, according to written archives.
