 Between the 1910s and the 1940s, many ethnic Pashtun herders settled in Afghan Turkestan.From the 1930s to the 1970s, after the ethnically Tajik Habibullah Kalakani attempted and failed to seize power in Afghanistan in 1929, ethnic Uzbeks and ethnic Tajiks lost hundreds of thousands of acres of pasture and cultivated land in northern Afghanistan.Afterwards, this land was sold or outright given to ethnic Pashtun settlers, further increasing Pashtun influence in northern Afghanistan.
