A country in Central Asia, one of the 'stans, formerly part of the Soviet Union, and long long before that, part of the one or the other Persian Empire. It is subject to the cliche that it actually is a Turkic country. It is therefore only appropriate for Tajikistan in future histories (and sometimes ATLs, too) to join a powerful Pan-Turkestan whenever it emerges. What? Never mind the fact that the Tajiks actually speak a variety of Persian.

See also Romania for a European country about which similar misconceptions exist.
