I tappeti di Arak sono assolutamente inconfondibili per il disegno, annodatura e struttura. Sono diversi gli schemi decorativi e vanno dal classico motivo a medaglione centrale al disegno floreale a tutto campo fino ad arrivare al campo di un unico colore.

Arak, previously known as Soltan-abad, is the center of Markazi province, Iran. Arak is built on the ruins of a small town called Daskerah, which was destroyed during the Mongol invasion of Persia. Modern Arak is a relatively new city on fertile lands, reestablished in 1795 with primary construct ending in 1852. The new city was founded and financed during the Qajar era by an Iranian Georgian Yusef Khan Gorji, a pro-Iranian Georgian warlord given refuge by Shah Muḥammad Khān Qājār (1742-1797) following a territorial dispute with his cousins who were supported by Imperial Russian Empress Catherine the Great. In the period between 1795 and 1797, Yusef Khan-e Gorji, renamed Yusef Khan-e Sepahdar by the Shah, settled his army in the fertile though poorly-controlled territory that would become modern Arak. Hostile tribes in this region had operated autonomously from Qajar rule. With the Persian Shah's approval, Yusuf Khan diverted the main river to drive out the hostiles and built the Soltan Abad fortress, or Baladeh, a war fortress to act as a buffer and serve as the foundation of what would become modern Arak. Yusuf Khan's organized military force was established in this region aptly named (or more accurately, re-named) "Persian Iraq" (Iraq-e ajam) from ancient times meaning 'smooth land'. According to historians, Yusef Khan built Arak from his own personal income and with the aid of affluents. The town would remain a military base and fortress until 1892. The Soltan Abad fortress had a thick wall surrounded by great moats, 7 meters deep. Eight towers were constructed around the town and the governmental building was established in its northern part. In 1891 deputy governor, Etemadol Saltaneh Mirza Hasan, repaired all of the shops, gardens and all government buildings in Soltan Abad's greater town and with the owners of industries from other towns, settled in Arak. Large portions of the town were annexed as personal property to the pre-existing army commanders though these were ultimately turned over to the state from 1918-1922. The evolution of the modern town name is from Soltan Abad fortress, to Soltan Abad, to Iraq-e Ajam (Persian-Iraq), and finally to its current name, Arak, in 1938.Under the rule of Reza Shah Pahlavi, main railways crossed along the city and later the south-north oil pipe line passed through the city, which lead to rapid growth. Great attention to the building of Arak during the Pahlavi dynasty led many to speculate its intended designation as the future capital of Iran^.
