The venkatam hill is believed to be a part of the celestial mount meru brought to the earth from vaikuntam by garuda (Lord's vehicle),say the puranas.The Hills are said to be a manifestation of Adi Sesha (the cosmic serpent).The Seven hills of the Tirumala are the said to represent the Seven hoods of Adi Sesha.
Many Alvars , Vaishnavacharyas and Saints have praised the Tirumala Hill with great devotion. Tirumala Mambi, a descendent of the great ascetic Narada, spent his whole life in serving the Lord.
References to the tirumala also found in several of Puranas. Tirumala is one of the 108 sacred shrines of the Sri Vaishanava tradition.According to the Puranas, Lord Vishnu stayed on the earth for some time in the Avatar of Swetha Varaham and rose out of pushkarini as Swayambhuva. His spouse Lakshmi Devi appeared in Thirucharnur. This Swwtha Varaha Avatharam was installed in the temple situated to the west of Swamy Pushkarni. The great religious leader Ramanujacharya visited this shrine on a pilgrimage and systematised the process of worship in accordance with the SriVaishnava that continues to date.
The Pallavas of Kanchipuram (9th century AD) ,Cholas of Tanjore (10 century) , Pandyas of mathura and Vijayanagara pradhans (14th & 15th centuries) were committed devotees of Lord Venkateswara. The statues of Sri Krishna Devaraya and his spouse stand in the premises of the temple. After the decline of Vijayanagara Empire, kings from various states like the king of Mysore and Gadwal, worshiped the lord as pilgrims and gifted various ornaments and valuables to the temple. Raghoji Bhonsle, the Maharastrian commander visited the temple and made a permanent arrangement regarding the regular pujas to be done to the Lord.
In 1843 the temple gave up administrative authority of Venkateswara Temple along with the temples in the village to the head of Hatthimji monastery in Tirumala. Till 1933 the administration of the temple had been wielded by the head of that monastery, Hathiram Mahantha.
In 1933 the Madras government appointed a Commission to Tirumala Tirupati Devasthanam through a special statutory authority to run the administration of the temple. In 1951 another Hindu Religious and endowment Act was made which felicitated the appointment of an executive officer and Board of trustees and they run the administration. The executive officers of this institution in the South have been maintaining administration.
