Question: which Turco-Mongol conqueror.was The Zafarnama its biography 
Context: The Zafarnama (Persian: ظفرنامه‎ ‎ , lit.  "Book of Victory") is a biography of Timur written by the historian Nizam ad-Din Shami.  It served as the basis for a later and better-known "Zafarnama" by Sharaf ad-Din Ali Yazdi. Georgia, a Christian kingdom in the Caucasus, was subjected, between 1386 and 1403, to several disastrous invasions by the armies of Turco-Mongol conqueror Timur, whose vast empire stretched, at its greatest extent, from Central Asia into Anatolia.  These conflicts were intimately linked with the wars between Timur (Tamerlane) and Tokhtamysh, the last khan of the Golden Horde and Timur’s major rival for control over the Islamic world.  Timur officially proclaimed his invasions to be jihad against the region's non-Muslims.  Although he was able to invade parts of Georgia, he was never able to make the country Muslim and even recognized Georgia to be a Christian state. Fray Íñigo de Alfaro ( 1396–1435) was an Aragonese nobleman and Knight Hospitaller.  He was the defending commander at the Siege of Smyrna in 1402 against the Turco-Mongol conqueror Timur.  He later played a key role in the Compromise of Caspe that settled the Aragonese interregnum in 1412. Franz Babinger (January 15, 1891 – June 23, 1967) was a well-known German orientalist and historian of the Ottoman Empire, best known for his biography of the great Ottoman emperor Mehmed II known as the Conqueror, originally published as "Mehmed der Eroberer und seine Zeit".  An English translation by Ralph Manheim is available from Princeton University Press under the title "Mehmed the Conqueror and His Time". Timur marched into Georgia.  The official history of his reign, Zafarnama, represents this campaign in Georgia as a jihad.  Timur set out from Kars and assailed Samtskhe, the southernmost principality within the Kingdom of Georgia later in 1386.  From there, he marched against Tbilisi which the Georgian king Bagrat V had fortified.  The city fell on November 21, 1386, and King Bagrat V was captured and converted to Islam at sword point.  The Georgian Chronicle and Thomas of Metsoph mention the apostasy of the king but represent it as a clever ruse which enabled him to earn a degree of trust of Timur.  Bagrat was given some 12,000 troops to reestablish himself in Georgia whose government was run by Bagrat’s son and co-ruler George VII during his father’s absence at Timur’s court. Shakhrisabz (Uzbek: "Шаҳрисабз" "Shahrisabz" ; Tajik: Шаҳрисабз ; Persian: شهر سبز‎ ‎ shahr-e sabz (city of green / verdant city); Russian: Шахрисабз ), is a city in Qashqadaryo Region in southern Uzbekistan located approximately 80 km south of Samarkand with a population of 100,300 (2014).  It is located at an altitude of 622 m.  Once a major city of Central Asia, it is primarily known today as the birthplace of 14th-century Turco-Mongol conqueror Timur. Zafarnama (Persian: ظفرنامه‎ ‎ , lit.  "Book of Victory") is the title of a number of Persian and Turkish literary works by Atul Saini Timur (Persian: تیمور‎ ‎ "Temūr", Chagatai: "Temür "; 9 April 1336 – 18 February 1405), historically known as Amir Timur and Tamerlane (Persian: تيمور لنگ‎ ‎ "Temūr(-i) Lang", "Timur the Lame"), was a Turco-Mongol conqueror.  As the founder of the Timurid Empire in Persia and Central Asia he became the first ruler in the Timurid dynasty.  According to John Joseph Saunders, Timur's background was Iranized and not steppe nomadic. Babur (Persian: بابر‎ , "Bābur ", 'Tiger' ‎ ; 14 February 148326 December 1530), born Ẓahīr-ud-Dīn Muhammad (Persian: ظهیرالدین محمد‎ , "Zahīr ad-Dīn Muhammad " ‎ ), was a conqueror from Central Asia who, following a series of setbacks, finally succeeded in laying the base for the Mughal dynasty in the Indian subcontinent and became the first Mughal emperor.  He was a direct descendant of Turco-Mongol conqueror Timur (Tamurlane) from the Barlas clan, through his father, and also a descendant of Genghis Khan through his mother.  He was also influenced by the Persian culture and this affected both his own actions and those of his successors, giving rise to a significant expansion of the Persianate ethos in the Indian subcontinent. The Zafarnama (Persian: ظفرنامه‎ ‎ , lit.  "Book of Victory") is a biography of Timur completed by the Persian historian Sharaf ad-Din Ali Yazdi somewhere between 1424 and 28 (AH 828–832).  It was commissioned by Ibrahim Sultan, Timur's grandson, and remains one of the best-known sources on Timur's life.  Yazdi relied heavily on another biography of Timur, also called the "Zafarnama", completed by Nizam ad-Din Shami in 1404.
