After liberation of Tabriz in 1603, Shah Abbas marched north to liberate rest of Greater Azarbaijan which was under Ottoman occupation since his grandfather Shah Ismail's defeat at the Battle of Chaldoran.
The Ottoman chief Sharif Pasha evacuated the Nakhjevan Castle and gathered all of his forces, around 12,000 soldiers at the Erivan Castle preparing for a long term siege. Nakhjevan citizens welcomed Zolfaghar Khan Karamanloo without a battle and the remaining guards at the castle surrendered. Ensued by this victory, Kurdish and Armenian leaders expressed allegiance to Shah Abbas against the Ottoman Empire. This was an important political success for the Safavid Empire.
In late February, the Iranian army reached Erivan which was a well-fortified city with three castles. Shah ordered his logistics to start casting cannons. Production of the third cannon was completed by Barkhordar Bey Toopchibashi on March, 26, 1604. They named last cannon Nosrat meaning victory after it helped conquer the smaller Kozchi Castle.
The new Erivan Castle was captured on May, 28, 1604 after a brief siege. Sharif Pasha and his soldiers surrendered without much resistance and their lives were spared. Sharif Pasha who was originally from Isfahan preferred to serve the Safavid court. He later settled in Mashhad with 100 of his relatives. The remaining soldiers who wished to return to their homeland were escorted to the Kars Castle. These acts of kindness and mercy towards enemy was recorded as a plus for Shah Abbas the Great and created much publicity for the Safavid Empire.
After the victory in Nakhjevan, Shah Abbas sent a courier to Allahverdi Khan asking him to terminate siege of Baghdad. The Baghdad governor Uzun Ahmet thought it was a good time to invade Iran from the southwest while the main Safavid army was busy in North. Upon receiving the news of the Ottoman invasion, local tribal leaders in Lorestan and Kurdistan gathered an army of 3000 men and faced them at the border and defeated the larger Ottoman army in a fierce battle and captured Uzun Ahmet. He was sent to Shah Abbas. Shah spared his life and let him go back but Uzun Ahmet became sick on his way home and died in Zanjan.
