Located along historic east-west routes, Kermanshah functions as Iran’s primary land bridge to Iraq. Its position in the Zagros foothills gives it strategic relevance for trade, military movement, and border security.

The city has long served as a logistical and administrative node on routes linking Tehran with Baghdad. Its predominantly Kurdish population places it at the intersection of Iranian state authority and transborder Kurdish dynamics.

Kermanshah’s position at the mouth of a major Zagros corridor has made it strategically significant since antiquity. The Bisotun inscription carved into a cliff face outside the city, commissioned by Darius the Great around 515 BC in three languages, records the Achaemenid king’s legitimacy and his defeat of rivals. Sassanid-era rock reliefs at Taq-e Bostan confirm the city’s continued ceremonial importance through the late antique period.

Through the Safavid and Qajar periods Kermanshah served as the principal regional centre for the Kurdish population and the western frontier with the Ottoman Empire. During the Iran-Iraq War it was a critical rear-area logistics hub for western front operations. After 2003 the opening of Iraq to trade and the autonomy of Iraqi Kurdistan elevated Kermanshah’s commercial and transit role substantially.

Kermanshah remains economically dependent on cross-border commerce, agriculture, and public-sector employment. It is strategically monitored due to Kurdish political sensitivities, proximity to Iraq, and its role as a staging area for western border security operations.
