Al-Hurr ibn Yazid al Tamimi (Arabic: الحر بن يزيد) was the general of the Ummayad army dispatched from Kufa, Iraq to intercept al-Husayn ibn Ali ibn Abu Talib. The newly appointed governor of Kufa, Ubayd Allah ibn Ziyad, issued the command to guard all entrances and exits to Kufa in order to intercept al-Husayn for an oath of allegiance to Yazid ibn Mu'awiya ibn Abu Sufyan of the Ummayad dynasty. Al-Hurr ibn Yazid al-Tamimi al-Yarbu'i was ordered along with his 1,000 soldiers to sanction al-Husayn and his followers and bring them to Kufa. Initially responsible for holding al-Husayn and his followers captive, al-Hurr died fighting on al-Husayn's behalf after decisions fueled by corrupt intentions surfaced from Ubayd Allah ibn Ziyad. Provided below is the lineage of al-Hurr and a detailed recital of events that will illuminate what led to al-Hurr's death on the 10th of Muharram 61 AH/680 AD. Al-Hurr's short but provocative mark on history spans less than one week's time, but is embedded with complex details and fatal turns of events that led to the death of al-Husayn during the Battle of Karbala.
Minor discrepancies of al-Hurr's tribal lineage appear in various historical accounts. The Encyclopedia of Islam gives his full title as "al-Hurr ibn Yazid ibn Nadjiya ibn Ka'nab ibn Attab ibn al-Harith ibn Amr ibn Hamman al Riyahi al Yarbu'i al Tamimi". In one account from al-Tabari, Zakariyya ibn Yaha al Darir describes al-Hurr as a descendent of Al-Yarbu'i Riyahi from the tribe of Banu Tamim located in Kufa, Iraq. This is the most commonly accepted lineage of al-Hurr conveying a condensed title of al-Hurr ibn Yazid al Tamimi. However, another account of al-Tabari transmitted by al-Husayn ibn Abd al-Rahman conveys the title of al-Hurr ibn Yazid al-Hanzali, deriving lineage a different clan, the Banu Nahshal. For the purpose of this entry, all references to al-Hurr ibn Yazid ibn Tamimi al Yarbu'i will be made as al-Hurr.
