Disasters with highest death tolls
Persian Famine of 1870–1872
Iran
The Great Persian famine of 1870–1872 was a period of mass starvation and disease in Persia between 1870 and 1872. There is no agreement among scholars as to the total number of deaths during the famine, although it is believed that it resulted a considerable decline in Iran's population. The death toll from this famine is estimated to be in the range of 1.5 million people.
