Second Treaty

A series of border incidents in the 1830s again brought Iran and the Ottoman Empire to the brink of war.

This treaty divided the disputed region between Iran and the Ottoman Empire and provided for a boundary commission to delimit the entire border. The boundary commission's work encountered several political setbacks but finally completed its task in 1914.
