[3] Tankiz was raised in Cairo and was later bought by Sultan Husam al-Din al-Lajin in 1296, becoming a mamluk (slave soldier) in his service until January 1299, when Lajin was killed.
[3] Thus, when an-Nasir Muhammad regained the sultanate later that year, Tankiz was given the rank of amir tabalkhanah (emir of forty mamluks).
[9] On an-Nasir Muhammad's instructions, Tankiz was then trained how to govern by Arghun an-Nasiri, the na'ib as-saltana (viceroy) of Egypt.
[9] He also held the additional title al-kafil al-mamalik al-shamiyya, which translates as "supreme governor of the noble provinces of Damascus.
[11] In 1315, Tankiz was dispatched by an-Nasir Muhammad as the supreme commander of Egyptian and Syrian mamluk regiments in an offensive to capture the Mongol-allied fortress of Malatya in Anatolia.
Tankiz led his army dressed in the clothes of a king and "on his horse, all was gold, even his hunting drum," according to Mamluk-era chronicler Ibn Sasra.
[13] Tankiz managed to conquer Malatya and successfully embarked on a number of raids against nearby Lesser Armenia, which was also allied with the Mongols.
[14] Tankiz compromised with the ulema (Muslim scholars) and agreed that 60 jurists would remain employed by the madrasa (Islamic law college).
[10] In March 1337, Tankiz had negotiated the release of two emirs of the Cairo Citadel, Tashtamur Akhdar and Qutlubugha al-Fakhri, who had been imprisoned by an-Nasir as a result of an alleged assassination plot.
[16] Throughout his rule, Tankiz engaged in several building works, "changing [sic] the face" of Damascus with the new public structures, according to historian Moshe Sharon.
[19] Other projects included various civil planning pursuits that controlled unorganized expansion, particularly in the northern and western parts of the city and the establishment of important streets, bridges and spaces to ease transportation and communication in the district.
[21] Simmering conflict between the two reached its apex in 1339 after Tankiz's request to hunt in Qal'at Ja'bar in northern Syria was rejected by an-Nasir Muhammad.
"[21] With Tankiz being in a strong position to launch a decisive revolt in Syria, an-Nasir Muhammad interpreted his words as a threat to usurp the throne.
In Damascus alone nearly 40 public institutions, including mosques and schools, were constructed or restored either under the direct orders of Tankiz or by various princes, judges and wealthy merchants.
Glass mosaics that previously existed in those structures (most dated from the Umayyad period) and had since worn down were given specific attention by Tankiz.
[1] In 1328-1330, Tankiz endowed a charitable foundation, madrasa (the Tankiziyya), and women's hospice (the Ribat an-Nisā’) in Jerusalem, near the Chain Gate.
[28][29] In honor of his wife (Khawand Sutayta bint Kawkabay al-Mansuri), Tankiz built a twin-domed mausoleum for her in Damascus called al-Turba al-Kawkabʾiyya,[30] which was completed five months after her death in 1330.
