Khurasan and Herat

Geography and Topography

Iran-zamin, ‘the land of Iran,’ means more than a place of habitation and extends beyond the present political entity.” For the multifarious peoples of Persia, this is the area where they “have maintained their special way of life through centuries of invasion, social change, and political turmoil. [It] is the birthplace and home of an unique Iranian culture—the product of an ancient relationship between diverse peoples and their homeland.” An integral geo-graphical, political, cultural, and economic constituent of Iran-zamin is the vast geographical expanse called Khurasan.

Geographical Khurasan is a long and narrow tract—somewhat like a trapezoid (the northern and southern limits are nearly parallel)—whose ill-defined boundaries stretch from the southeastern littoral of the Caspian Sea to the Hindu Kush. The limits of political-cultural Khurasan are nebulous, but generally admitted to includ e territories influenced by Persian culture: parcels in Turkmenistan, Uzbekistan, and Tajikistan. The tract is bounded in the north by the River Oxus (Amū Darya, Jayhūn) and the Black Sands (Qara-Qum) desert; in the southwest/south by two salt deserts: Dasht-i Kawīr and Dasht-i Lūt. Quhistān, Sistān, Bamiyān, and Ghūr are at Khurasan’s southwestern/southern limits; Qandahar and Ghazni, the southeast. Khurasan’s forbidding topographical features were eloquently described by Edmund Bosworth:

The land is ostensibly inhospitable; however, water originating in mountains, and held in underground water basins, is plentiful. Three millennia ago, the ingenious Iranian mind conceived a scientific marvel, the kārīz, which transports water from subterranean reservoirs to thirsty farmers and farmlands. It is costly and labor-intensive to excavate a kārīz, more so the farther the mother-well (chāh-mādar) is from the outlet. A kārīz requires frequent maintenance to prevent silting/collapse.
