Tajikistan first passed a law on refugees in 1994, bringing them into partial compliance with the 1951 Convention Relating to the Status of Refugees and the 1967 Protocol which amended it. However, during the 1990s, few Afghan refugees chose Tajikistan as their destination; most were people associated with Mohammad Najibullah's fallen Democratic Republic of Afghanistan and Republic of Afghanistan administrations. Aside from political motivations, droughts were another major driver of migration. By May 2001, the Committee of Afghan Refugees claimed there were 4,000 refugees in Dushanbe alone, while the Tajik government put the figure at three to four times that number. These early refugees were primarily ethnic Uzbeks and Tajiks from northern Afghanistan.
