Herat, a frontier vassalage barely under Iranian control, was seen by the Qajar dynasty as an integral part of the Guarded Domains of Iran.

The latter received an ultimatum from Abbas Mirza at the beginning of 1833 with two options: either have the name of the Iranian shah (king) mentioned on coin engravings and Friday prayers, pay taxes, and release hostages, or relinquish Herat and appear at the Iranian court.

[4] Abbas Mirza wanted to capture to Herat to show his military capabilities, but also to advance the eastern objectives of the Russian Empire, who was pressuring him.

[1] As a result, Kamran Mirza made an alliance with the British, whose operatives convinced him to oppose a military takeover by Iran.

A treaty was shortly made afterwards, in which Kamran Mirza was required to send one of his sons as a hostage, have the name of the Iranian shah mentioned on coin engravings and Friday prayers, and provide 15,000 toman and 50 rolls of cashmere wool as a "gift".
