Sogdiana, Bactria, Merv and Khorezm were the four principal divisions of Ancient Central Asia inhabited by the ancestors of the present-day Tajikistani Tajiks.
Tajikistan was part of the Bactria-Margiana Archaeological Complex in the Bronze Age, candidate for Proto-Indo-Iranian or Proto-Iranian culture.
Bactria was located in northern Afghanistan (present-day Afghan Turkestan) between the mountain range of the Hindu Kush and the Amu Darya (Oxus) River and some areas of current south Tajikistan.
Notable contact was made with local peoples when the envoys of the Han dynasty journeyed to this area in the 2nd century BC.
Beginning in 651, the Arabs organized periodic marauding raids deep into the territory of Transoxania, but it was not until the appointment of Ibn Qutaiba as Governor of Khorasan in 705, during the reign of Walid I, that the Caliphate adopted the policy of annexing the lands beyond the Oxus.
The entire region thus came under the control of the Caliph and of Islam, but the Arabs continued to rule through local Soghdian Kings and dihqans.
While their predecessors the Umayyads (661–750) were little more than leaders of a loose confederation of Arab tribes, the Abbasids set out to build a huge multi-ethnic centralized state that would emulate and perfect the Sassanian government machine.
The Samanid dynasty ruled (819–1005) in Khorasan (including Eastern Iran and Transoxiana) and was founded by Saman Khuda.
In 900, Ismail defeated the Saffarids in Khorasan (area of current Northwest Afghanistan and northeastern Iran), while his brother was the governor of Transoxiana.
The cities of Bukhara (the Samanid capital) and Samarkand became centres of art, science, and literature; industries included pottery making and bronze casting.
However, with the oncoming encroachment of Muslim Turks, the Samanids lost their domains south of the Oxus river which were taken by Ghaznavids.
He was a member of the Turkicized Barlas tribe, a Mongol subgroup that had settled in Transoxiana after taking part in Genghis Khan's son Chagatai's campaigns in that region.
During this period, he received an arrow-wound in the leg, as a result of which he was nicknamed Timur-e Lang (in Dari) or Timur the Lame.
[2][9] The expansion was motivated by Russia's economic interests and was connected with the American Civil War in the early 1860s, which severely interrupted the supply of cotton fiber to the Russian industry and forced Russia to turn to Central Asia as an alternative source of cotton supply as well as a market for Russian made goods.
The Russian regime in the 1870s attempted to switch cultivation in the region from grain to cotton (a strategy later copied and expanded by the Soviets).
The emir retained his throne as a vassal of Russia and with Russian help he established control over Shahr-e Sabz, the mountainous regions in the upper Zeravshan Valley(1870) and the principalities of the western Pamir (1895).
Further violence occurred in July 1916 when demonstrators attacked Russian soldiers in Khujand over the threat of forced conscription during World War I.
Despite Russian troops quickly bringing Khujand back under control, clashes continued throughout the year in various locations in Tajikistan.
The movement's roots lay in the anti-conscription violence of 1916 that erupted when the Russian Empire began to draft Muslims for army service during World War I.
Turkestani Muslim political movements attempted to form an autonomous government in the city of Kokand, in the Ferghana Valley.
The fortunes of the decentralized movement fluctuated throughout the early 1920s but by 1923 the Red Army's extensive campaigns dealt the Basmachis many defeats.
After major Red Army campaigns and concessions regarding economic and Islamic practices in the mid-1920s, the military fortunes and popular support of the Basmachi declined.
[17] Two rounds of Soviet purges directed by Moscow (1927–1934 and 1937–1938) resulted in the expulsion of nearly 10,000 people, from all levels of the Communist Party of Tajikistan.
[14] During 1957–58 Nikita Khrushchev's Virgin Lands Campaign focused attention on Tajikistan, where living conditions, education and industry lagged behind the other Soviet Republics.
The glasnost policy of openness initiated by Mikhail Gorbachev offered disgruntled Tajiks a chance to voice their grievances.
Post-Soviet countries have signed a series of treaties and agreements to settle the legacy of the former Soviet Union multilaterally and bilaterally.
The non-Muslim population, particularly Russians and Jews, fled the country during this time because of persecution, increased poverty and better economic opportunities in the West or in other former Soviet republics.
In October 2020, President Emomali Rahmon was re-elected for next seven-year period with 90 per cent of the votes, following a tightly controlled and largely ceremonial election.
