Factory means the place where the workshop is generally located for the use of common people but in the middle ages the sound of this word was very different. Medieval historians have used it in a broader sense. According to which the factory included other things besides the work schools. Such as personal services of the royal court of Sultan and animal fences etc. The Mughals used the word Bayutat, which is the plural of the Arabic language word Bait. The meaning of Bait is home. Hence the meaning of Bayutat in the context of Gharbar was sufficiently clear to the Mughal administrators. Factories or Bayutat as the name of this department included their factories and stores that the government used to maintain for the use of the state. From pearl and diamond, gems to swords, to guns and heavy ammunition, the purchase and maintenance was the responsibility of this department. Bayutat were also responsible for the maintenance of pony animals carrying loads, horses, elephants for the army and other animals for royal hunting. This department not only procured and stored all kinds of goods but was also the largest agency for the manufacture of weapon and luxuries for the war. Although the ownership and management of the Bayutat was in the hands of the state but it was completely run commercially.
