The current Tajik Republic hearkens back to the Samanid Empire (A.D. 875-999), which ruled what is now Tajikistan as well as territory to the south and west, as their role model and name for their currency. During their reign, the Samanids supported the revival of the written Persian language in the wake of the Arab Islamic conquest in the early 8th century and played an important role in preserving the culture of the pre-Islamic Persian-speaking world. They were the last Persian-speaking empire to rule Central Asia.
After a series of attacks beginning in the 1860s during the "Great Game" between the British Empire and the Russian Empire for supremacy in Central Asia, the Tajik people came under Russian rule. This rule waned briefly after the Russian Revolution of 1917 as the Bolsheviks consolidated their power and were embroiled in a civil war in other regions of the former Russian Empire. As the Bolsheviks attempted to regain Central Asia in the 1920s, an indigenous Central Asian resistance movement based in the Ferghana Valley, the "Basmachi movement," attempted to resist but was eventually defeated in 1925. Tajikistan became fully established under Soviet control with the creation of Tajikistan as an autonomous Soviet socialist republic within Uzbekistan in 1924, and as one of the independent Soviet socialist republics in 1929.
