King Marthanda Varma of Travancore defeats the Dutch East India Company at the Battle of Colachel, effectively bringing about the end of the Dutch colonial rule in India.

Anizham Thirunal Marthanda Varma was the founding monarch of the southern Indian Kingdom of Travancore from 1729 until his death in 1758. He was succeeded by Rama Varma (1758–98).

The kingdom of Travancore, also known as the Thiruvithamkoor Kingdom and Travancore State, was a kingdom that lasted from c. 1729 until 1949. It was ruled by the Travancore royal family from Padmanabhapuram, and later Thiruvananthapuram. At its zenith, the kingdom covered most of the south of modern-day Kerala and the southernmost part of modern-day Tamil Nadu with the Thachudaya Kaimal's enclave of Irinjalakuda Koodalmanikyam temple in the neighbouring kingdom of Cochin. However Tangasseri area of Kollam city and Anchuthengu near Attingal in Thiruvananthapuram were parts of British India.

The United East India Company, commonly known as the Dutch East India Company, was a chartered trading company and one of the first joint-stock companies in the world. Established on 20 March 1602 by the States General of the Netherlands amalgamating existing companies, it was granted a 21-year monopoly to carry out trade activities in Asia. Shares in the company could be purchased by any citizen of the Dutch Republic and subsequently bought and sold in open-air secondary markets. The company possessed quasi-governmental powers, including the ability to wage war, imprison and execute convicts, negotiate treaties, strike its own coins, and establish colonies. Also, because it traded across multiple colonies and countries from both the East and the West, the VOC is sometimes considered to have been the world's first multinational corporation.

The Battle of Colachel was fought on 10 August 1741 [O.S. 31 July 1741] between the Indian kingdom of Travancore and the Dutch East India Company. During the Travancore-Dutch War, King Marthanda Varma's (1729–1758) forces defeated the Dutch East India Company's forces led by Admiral Eustachius De Lannoy on 10 August 1741. The Dutch never recovered from the defeat and no longer posed a large colonial threat to India. Travancore triumphed in the war thanks to the exceptional military efforts of the Travancore Nair Brigade at sea, along with the leadership of three Nair commanders—Arumukhan Pilla, Nanu Pilla, and Chembaka Raman Pilla—on land.
