Krishnadevaraya's ascension to the throne marked a transformative phase in the Vijayanagara Empire, a South Indian realm that had been experiencing both cultural flourishing and military challenges. Born into the Tuluva dynasty, he became the third ruler after his brother's reign ended. His rule began in 1509 amidst various regional conflicts and threats from the Deccan sultanates, as well as the ongoing struggles against the growing influence of the Portuguese along the western coast of India.

One of Krishnadevaraya's first notable actions was to consolidate power and ensure stability within the empire. He took steps to strengthen military infrastructure, resulting in successful campaigns against rival kingdoms. His military endeavors expanded Vijayanagara's borders significantly, allowing for an influx of wealth and resources which facilitated further development within the empire. Krishnadevaraya was also an astute administrator, implementing policies that improved governance and administration.

In addition to military and administrative reforms, Krishnadevaraya is celebrated for his patronage of the arts and culture. His court became a hub for Telugu literature and art, inviting poets and scholars to his court, including the famed poet Allasani Peddana, who is often hailed as the 'A adi Kavi' or the first poet of Telugu literature. This period saw the construction of grand temples and architectural works that symbolize this cultural renaissance. His reign laid the groundwork for subsequent rulers and contributed to the establishment of the Vijayanagara Empire as a dominant cultural force in India.
