History.
Sawantwadi state was founded in 1627 by Khem Sawant I, later becoming a vassal state of the Sultanate of Bijapur. Khem Sawant II made Sundarwadi his capital which later got the name of Sawantwadi as the rulers were known as Sawants. 
The Sawant dynasty, the head of the Sawantwadi State, arrived in the province in the 16th century. This dynasty ruled over South Konkan for a long time. Their career is full of bravery. 
Sawants of Kudal are descendants of the Sisodia Rajput family of Udaipur (Rajasthan). These families are considered to be the kings of the Sun dynasty. According to available references these descendants of the Sisodia dynasty ruled at that time by establishing a throne at Chittod in Mewar province. Udaipur is a city in the same province.
Mang Sawant of this family was the first to come here in South Konkan. He is considered to be the progenitor of the Sawantwadi dynasty. He came to this province with the army of King of Vijayanagar. 
Initially, he was stationed 
at Gandharvagad in Chandgad taluka for some time. Therefore, he was also known as Chandgudhadhipati. 
After coming to Konkan, he first established his stronghold at Hodawade (Tal. Vengurle). He defeated the local chiefs who had influence in the area at that time. His fame gradually spread in the province.
In 1580, Mang Sawant and Kudaldeshastha Prabhu's general Dev Dalvi jointly declared war on Kudal province. The purpose behind this was to establish the power. The lord of Kudal got help from the Bijapur Sultan. Mang Sawant was killed in a battle between the two armies at Hodawade. 
On 7 April 1765 Savantvadi State became a British protectorate.
Sawantwadi acceded to the Dominion of India on 15 August 1947, becoming part of Bombay State in 1948.
