The Bahmani–Vijayanagar War (1398)[3] of 1398 marked the military conflicts between the Bahmani Sultanate under Tajuddin Firuz Shah and the Vijayanagar empire under Harihara II.

The war was ignited by the invasion of Raichur by Prince Bukka and Harihara II, who capitalized on the internal conflicts within the Bahmani Sultanate's northern region.

Exploiting the ensuing disorder, Firuz Shah launched an attack on Vijayanagar, compelling Harihara to lay down his arms under pressure from the Brahmins, whose families had been enslaved by the Bahmanis.

During a severe famine lasting eight years (1387-1395 A.D.), the Sultan swiftly organized relief efforts and established numerous orphanages to aid those in need.

Firuz Shah successfully suppressed the rebellion at Sagar, with assistance from certain Hindu chiefs, most notably Bhairon Singh, who was the progenitor of the Kingdom of Mudhol.

[9] Taking advantage of the internal struggles faced by the Bahmanis, Harihara II decided to secure his flank by persuading Katya Vema of Rajamundry to join forces with him.

[1] Meanwhile, Prince Bukka II of Vijayanagar, with 80,000 cavalry and additional forces of Musketeers, subdued the Velama chiefs of Telangana, who had a treaty relationship with the Bahmanis.

The rebellion at Kherla diverted Firuz Shah's attention, prompting him to send a large number of troops to the north.

Additionally, a flood occurred in the Krishna River due to the rainy season, preventing either army from crossing it.

[10] During this time, an officer of the Bahmani named Qazi Sirajuddin, though initially appointed for his judicial duties, displayed more prowess in military matters.

He proposed crossing the river with a small band of performers who could easily gain entry into the disorderly camp of the enemy.

By assassinating either Harihara or his son, they could sow chaos and provide an opportunity for the Bahmani army to cross under the cover of darkness.

[10] He and his small group crossed the river disguised as beggars and gained admission to the house of a female singer who regularly performed at the Vijayanagara camp in the evenings.

Suddenly, Sirajuddin rushed forward and struck down the prince, while his two confederates dealt with the minister, other spectators, and torch-bearers.

Meanwhile, upon the first signs of disturbance, their companions had attacked and killed the same guards, allowing the entire group to flee to safety and await the outcome of their mission.

[15] Harihara II then laid down his arms and entered into negotiations with the Malik Na'ib, who had returned after devastating the southern provinces.

A treaty was drafted, stipulating that the Bahmani Sultan would release all the prisoners captured, and in return, Harihara would pay ten lacs of huns into the royal treasury.
