Portuguese forces are defeated by the Kingdom of Kandy at the Battle of Randeniwela in Sri Lanka.
The Battle of Randeniwela was a battle fought on 25 August 1630 in the SinhalesePortuguese War. It was fought between Portuguese Empire and King Senarth's youngest son Prince Maha Astana, who would later become Rajasinghe II against Portuguese forces commanded by then Governor Constantinu De S de Noronha. It was fought at Randeniwela near Wellawaya, a place close to the town of Badulla. The battle broke off when Constantino de S launched the invasion via Badulla. The Portuguese army suffered a complete rout subsequent to a mass defection by its Lascarin (local militia) contingent.
The Kingdom of Kandy was a monarchy on the island of Sri Lanka, located in the central and eastern portion of the island. It was founded in the late 15th century and endured until the early 19th century.Initially, a client kingdom of the Kingdom of Kotte, Kandy gradually established itself as an independent force during the tumultuous 16th and 17th centuries, allying at various times with the Jaffna Kingdom, the Madurai Nayak dynasty of South India, Sitawaka Kingdom, and the Dutch colonizers to ensure its survival.From the 1590s, it was the sole independent native polity on the island of Sri Lanka and through a combination of hit-and-run tactics and diplomacy kept European colonial forces at bay, before finally falling under British colonial rule in 1818.
The kingdom was absorbed into the British Empire as a protectorate following the Kandyan Convention of 1815, and definitively lost its autonomy following the Uva Rebellion of 1817.
