The origins of Abhar are rooted in deep antiquity, when the first settled communities began to form on the fertile lands of northwestern Iran. Archaeological finds in the city's vicinity indicate that people inhabited these territories as far back as the Median Kingdom, attracted by the abundance of water from the Abhar-Rood River.
\nMost historians link the official establishment of the city as a significant center to the reign of the Sassanid dynasty. It is believed that large-scale construction began in the 4th century under King Shapur II, who recognized the area's strategic location. The city was envisioned as an important outpost, controlling communication routes and ensuring the region's food security through an advanced irrigation system.
\nA key factor in the survival and prosperity of Abhar was its unique hydraulic engineering. The use of karizes (underground channels) allowed arid lands to be transformed into flourishing gardens and vineyards. By the early Middle Ages, the city was already mentioned in the records of Arab geographers as a wealthy and fortified center, renowned for its crafts and agricultural products.
