The Kurdish homelands have traditionally been largely mountainous, landlocked areas, less open to outside influences and connections than surrounding areas. This meant they were late in developing a modern, cohesive, nationalist program, in contrast to their neighbors. Even after the consolidation of modern Turkey, Iran, Iraq, and Syria, Kurdish activism and resistance remained localized and heavily shaped by the Sufi orders and tribal confederations to which they traditionally belonged. And Kurds have been divided among themselves - not just politically as minorities into four different states, but linguistically, tribally, socially, and to a small degree confessionally. So pan-Kurdish sentiment is a very modern, recent phenomenon that has developed too late to overcome the established order in the region.
