The chequred history of Goa is marked by many incidents and the authority of Goa has always kept changing. The change of hands can be noted from the time before Jesus Christ was born. The history of Goa travels back into 3rd century BC when it was under the Mauryan dynasty. Goa was ruled by Buddhist emperor Ahsoka and the foundation of Buddhism was laid during this era by Buddhist monks. Following the rule of Ashoka several other rulers enjoyed their rule over Goa such as Chutus of Karwar,Western Kshatrapas, Abhiras of Maharashtra, Bhojas from Yadav clan of Gujarat, and Konkan Mauryas of Kalachuris. Later on, rule of Chalukyas of Badami and Rashtrakutas were also witnessed by Goa.
The place went under Delhi Sultanate in 1312, however the control on Goa was quite poor and soon Delhi Sultanate lost its control to Vijaynagara Empire.
The arrival of Portuguese colonizers forced Hindu rulers to leave the authority and officially they were defeated on 1510. Since then Goa has been ruled by Portuguese colonizers and they refused to leave Indian land even after several years after India’s Independence in 1947. Eventually, on December 1961, operation Vijay conducted by Indian Army won over Goa and it was made a part of India.
