There is an evident error in a date:
"In 1456 Abdur Rahman arrested Syed Jafar who was chief of Sheikh Ali Hazara and jailed him in Mazar-e-Sharif. The first Hazara uprising was during 1888 - 1890. When Abdur Rahman's cousin, Mohammad Eshaq, revolted against him, the Sheikh Ali Hazaras joined the revolt. The revolt was short lived and crushed as the Emir extended his control over large parts of Hazarajat. Sheikh Ali Hazaras had allies in two different groups, Shia and Sunni. Abdur Rahman took advantage of the situation, pitting Sunni Hazaras against Shia Hazaras, and made pacts among Hazaras.
"After all the Sheikh Ali Hazara chiefs were sent to Kabul, opposition within the leadership of Sawar Khan and Syed Jafar Khan continued against government troops, but at last were defeated. Heavy taxes were imposed and Pashtun administrators were sent to occupied places, where they subjugated the people with many abuses.[6] The people were disarmed, villages were looted, local tribal chiefs were imprisoned or executed, and the best lands were confiscated and given to Pashtun nomads (Kuchis).[6][19]
"The Second uprising occurred in 1890s - 1893. The cause of the uprising was the rape of the wife of a Hazara chief by 33 Afghan soldiers. The soldiers had entered their house under the pretext of searching for weapons and raped the chief's wife in front of him.[19] The families of the Hazara chief and his wife retaliated against the humiliation and killed the soldiers and attacked the local garrison, where they took back their weapons. Several other tribal chiefs who supported Abdur Rahman now turned against him and joined the rebellion which rapidly spread through the entire Hazarajat. In response to the rebellion, the Emir declared a "Jihad" against the Shiites and raised an army of 40,000 soldiers, 10,000 mounted troops, and 100,000 armed civilians (most of which were Pashtun nomads).[19] He also brought in British military advisers to assist his army.[19] The large army defeated the rebellion at its center, in Oruzgan, by 1892 and the local population was severely massacred."
Since Abdur Rahman is still active in the 1890s, he can't have arrested Syed Jafar in 1456!! I should have guessed 1856 was meant; but even this seems too early. Someone knowledgeable in this field should look into the matter and make the necessary correction.
