Lashkargah has a long history, possibly dating back to the time of the ancient
Achaemenid Empire. One of the oldest historical sites in the city is the
Fort of Bost, which is believed to be over 3,500 years old. The religion of
Islam first arrived to Bost in or about 661 AD. The city was rebuilt and expanded using American
urban planning, with broad tree-lined streets and brick houses with no walls separating them from the street. In the wake of the Soviet invasion of 1979 and the long
Afghan civil war, the trees mostly came down and walls went up. The massive Helmand irrigation project created one of the most extensive farming zones in southern Afghanistan, opening up many thousands of hectares of desert to human cultivation and habitation. Citizens from many parts of the country began moving to the Lashkargah area for job opportunities and a better life. The project focused on three large canals: the Boghra, Shamalan, and Darweshan. Responsibility for maintaining the canals was given to the
Helmand and Arghandab Valley Authority, a semi-independent government agency whose authority (in its heyday) rivaled that of the provincial governors. Militants raised the flag of the
Islamic Emirate of Afghanistan at the city's eastern entrance but withdrew following a few days after the United States agreed to halt its airstrikes on the Taliban near Lashkargah. After several weeks of fighting in the
Battle of Lashkargah, the city was captured by the Taliban on 13 August 2021, becoming the fourteenth provincial capital to be seized as part of the wider
2021 Taliban offensive. ==Geography==
