saints) of that time. Like the Virashaiva movement of the 12th century, this movement presented another strong current of devotion, pervading the lives of millions. The haridasas represented two groups, the Vyasakuta and Dasakuta, the former being required to be proficient in the Vedas, Upanishads and other Darshanas, while the Dasakuta merely conveyed the message of Madhvacharya through the Kannada language to the people in the form of devotional songs (Devaranamas and Kirthanas). The philosophy of Madhvacharya was spread by eminent disciples such as Naraharitirtha, Jayatirtha, Sripadaraya, Vyasatirtha, Vadirajatirtha and others. Vyasatirtha, the guru (teacher) of Vadirajatirtha, Purandaradasa (Father of Carnatic music) and Kanakadasa earned the devotion of King Krishnadevaraya. The king considered the saint his Kuladevata (family deity) and honoured him in his writings. During this time, another great composer of early carnatic music, Annamacharya composed hundreds of Kirthanas in Telugu at Tirumala – Tirupati, in present-day Andhra Pradesh. The Vijayanagara Empire created an epoch in South Indian history that transcended regionalism by promoting Hinduism as a unifying factor. The empire reached its peak during the rule of Sri Krishnadevaraya when Vijayanagara armies were consistently victorious. The empire annexed areas formerly under the Sultanates in the northern Deccan and the territories in the eastern Deccan, including Kalinga, while simultaneously maintaining control over all its subordinates in the south. Many important monuments were either completed or commissioned during the time of Krishna Deva Raya. Vijayanagara went into decline after the defeat in the Battle of Talikota (1565). After the death of Aliya Rama Raya in the Battle of Talikota, Tirumala Deva Raya started the Aravidu dynasty, moved and founded a new capital of Penukonda to replace the destroyed Hampi, and attempted to reconstitute the remains of Vijayanagara Empire. Tirumala abdicated in 1572, dividing the remains of his kingdom to his three sons, and pursued a religious life until his death in 1578. The Aravidu dynasty successors ruled the region but the empire collapsed in 1614, and the final remains ended in 1646, from continued wars with the Bijapur Sultanate and others. During this period, more kingdoms in South India became independent and separate from Vijayanagara. These include the Mysore Kingdom, Keladi Nayaka, Nayaks of Madurai, Nayaks of Tanjore, Nayakas of Chitradurga and Nayak Kingdom of Gingee – all of which declared independence and went on to have a significant impact on the history of South India in the coming centuries.
