In many accounts, Timmayya is described as a Malabari pirate. However, others say he was of aristocratic descent.
According to an article by BS Shastri in Proceedings of the Indian History Congress, Vol. 39, Volume I (1978), “The Portuguese regarded him a corsair and man of low sort. In reality, however, he was a man of high status and birth. He was the admiral of the Vijayanagara fleet... a princess of Gersoppa [in today's Karnataka] was his wife. He appeared a pirate to the Portuguese because he used to attack and loot those merchantmen who insisted on sailing to Goa and other enemy ports. This he did on the orders of the emperor of Vijayanagara.”
While some historians say that Albuquerque attacked Goa mainly because Timmayya advised him to, others believe that the Portuguese commander may already have been planning the attack, and Timmayya's inputs just helped him decide the timing.
And why did Timmayya want Goa attacked? Shastri writies, “Emperors of Vijayanagara had an eye on the territory ever since they had lost it to the Bahmanis in 1472... As a matter of fact, Timmayya had imperial instructions to weaken Goa by depriving it of its commerce.”
It is also believed that Hindus from Goa had written to Timmayya to liberate Goa from the Muslims, and realising he would be unable to do so alone, he decided to take the help of the Portuguese. However, if Timmayya had hoped that the island would be handed over to him after conquest, he was wrong. Albuquerque appointed him to a relatively small position, and set about “settling” Goa, by asking Portuguese men to marry local women and start lives here.
