Before the World War I, Zahedan was a small village named Dez Ap where Beluch locals resided and got the required water for drinking and agriculture by digging Qanats. Before that, the locals lived around a fortress. After the assassination of Naser al Din Shah, and the weakness of the Qajar Empire, the local Baluch governors gained power and got the control of the region. This caused the war between Doost Mohammad Khan the Baluch governor of the area and the military army of central Iran. After Doost Mohammad Khan got prisoned in Tehran, the central army got resided in Dez Ap and as a result of this, this village faced many political and economic changes. Because of being close to Afghanistan and Pakistan and also having a good situation for trading with India, the authorities of Iran stablished offices like the Customs office.
