Treaty · 1847
The Ottoman–Iranian border remained unsettled after the First Treaty of Erzurum (1823). According to the TDV article on Iran, the border regions saw new clashes in 1833–1842, which ended with the Ottoman–Iranian treaty signed at Erzurum in 1847. The treaty left the plain of Qasr-e Shirin to Iran and its hill country to the Ottomans; Iran renounced its claim to Sulaymaniyah, and the Ottoman state recognised Mohammerah (Khorramshahr) and the island of Khidr (today's Abadan) as Iranian territory. In this period permanent Ottoman and Iranian missions were opened in Tehran and Istanbul.
