Barlas trace their origin to Qarchar Barlas, head of one of Chaghadai's regiments. According to The Secret History of the Mongols—a 13th century epic written during the reign of Ögedei Khan—Qarchar Barlas was a descendent of the legendary Mongol warlord 'Bodonchir (Bodon Achir; Bodon'ar Mungqaq) who was also considered to be the direct ancestor of Genghis Khan. After the Mongol conquest of Central Asia, the Barlas settled in Turkistan (which then became also known as Moghulistan - "Land of Mongols") and intermingled to a considerable degree with the local Turkic and Turkic-speaking population, so that at the time of Timur's reign the Barlas had become thoroughly Turkicized in terms of language and habits. Additionally, by adopting Islam, the Central Asian Turks and Mongols also adopted the Persian literary and high culture which had dominated Central Asia since the early days of Islamic influence. Persian literature was instrumental in the assimilation of the Timurid elite to the Perso-Islamic courtly culture The word Mīrzā is derived from the Persian term ‘Amīrzāde which literally means "child of the ‘Amīr" or "child of the leader" in Persia. ‘Amīrzād in turn consists of the Arabic title ‘Amīr (engl. Emir), meaning "commander", and the Persian suffix -zād, meaning "birth" or "lineage". The title Mirza was most commonly used by the Turkic clan called Barlas. The Barlas people were the chief tribe of the Timurids and used Mirza as a title before the given name and Baig (also spelt 'Beg') as the surname for all the patriarchs. Thus creating the Mirza-Baig lineage. Mirza titles  were given by the kings, sultans or emperors to their sons and grandsons, or even distant kins. Noblemen loyal to the kings also received this Noble titles, although their usage differed. The name "Baig" is derived from the Turkic word Beg, or Bey, which means chief or lord (i.e. leader/commander). The spelling 'Baig' was most probably popularized, for ease of pronunciation, during the British colonial rule of the Indian Subcontinent. Baig was also a title given to honorary members of the Barlas clan, and was used as the family name for their children. Chughtai area in 13th Century ( see below)   The name Chughtai is a distorted form of Chaghadai, which comes from the Mongol Chagan (white) and the suffix –dai. The word Chaghadai thus means he who is white. The clan gets its name from Chagatai Khan, a son of the legendary Genghis Khan. The mother of Babar, the founder of the Mughal dynasty in South Asia, belonged to the Chughtai clan.                     In order to study the movement of Barlas clan let us study the historical record of Mughal emperors. Mughal emperors were descendants of the Timurids (1370-1405) the Barlas clan (see below):   As per history channel The dynasty was founded by a Chagatai Turkic prince named Babur (reigned 1526–30), who was descended from the Turkic conqueror Timur on his father's side and from Chagatai, second son of the Mongol ruler Genghis Khan, on his mother's side"    Timur's son, Miran Shah (1366 - April 1408)( also a town in Pakistan), and was granted governorship of Qandahar in 1383. That same year, he destroyed a rebellion against Timurid authority by the Kartids.   In 1396 Miran Shah was given control of Azerbaijan, principally the cities of Soltaniyeh, the former capital of the Ilkhans, and Tabriz. In the summer of 1398 he marched from Tabriz with the goal of subduing the Jalayirids of Baghdad, but was forced to call off the expedition. Meanwhile, rumors had come to Timur that his son was planning to betray him. In 1399 Timur sent a force under his nephew Sulaiman Shah to summon Miran Shah. The latter came with Sulaiman Shah willingly back to his father, where he was deposed of his governorship and assigned to his father's company for four years. His friends and advisors were executed.   The line of Miran Shah continued to play a prominent role in the remnants of the Timurid Empire, when Abu Sa'id came to power in Transoxiana. He is also the ancestor of Babur, the founder of the Mughal Empire.    Zahir ud-din Muhammad Babur learned about the riches of Hindustan and conquest of it by his ancestor, Timur Lang, in 1503 at Dikh-Kat, a place in the Transoxiana region. It is an ancient name used for the portion of Central Asia corresponding approximately with modern-day Uzbekistan, Tajikistan and southwest Kazakhstan.   Babur was the fruit of two greatest conquerors of Central Asia (connected to the family of Timur and Jenghiz Khan).  Babur became the king of Farghana at the age of eleven, as soon as his father died.  Soon after ascending the throne of Farghana, Babur annexed Samarkand, but fell ill the same year.  His ministers gave up hope of Babur's recovery, and  put his brother Jahangir on the throne of Farghana.  But Babur miraculously recovered to see Jahangir on the throne.  Jahangir had firmly established by then, and on the other side, Samarkand was occupied  by his cousin Ali.  Babur thus became wanderer for almost one year, without kingship.   A year later, Babur captured the capital of Farghana and Samarkand but lost in the same year to Uzbegs.  Babur was thus left with nothing, and aimed for his luck there onwards.   Meanwhile, the political situation in Kabul gave him a opportunity to set his foot in Kabul and managed to rule Kabul from 1504 AD till 1520 AD.  It is during the his reign he regained Samarkand and Bukhara but utterly failed in retaining it.  This disappointment led him to eye on India than on the lost land.    In his memoirs he wrote that after he had acquired Kabul (in 1514), he desired to regain the territories in Hindustan held once by Turks. He started his exploratory raids from September 1519 when he visited the Indo-Afghan borders to suppress the rising by Yusufzai tribes. He undertook similar raids up to 1524 and had established his base camp at Peshawar. In 1526, Babur defeated the last of the Delhi Sultans, Ibrahim Shah Lodi, at the First Battle of Panipat. To secure his newly founded kingdom, Babur then had to face the formidable Rajput Rana Sanga of Chittor, at the Battle of Khanwa. Rana Sanga offered stiff resistance but was defeated.
