He finally delivered the Mangalore fort to Tipu when the British capitulated on 30 January 1784.
On 11 March 1784, Tipu and the British East India Company signed the Treaty of Mangalore, thus bringing an end to the Second Anglo-Mysore War.
These migrants were welcomed by the native Bednore rulers of Canara for their agricultural skills.
They were followed by a second major wave precipitated by the Portugal–Adil Shahi wars between 15. George, by 1686, Seringapatam, capital of the Kingdom of Mysore, was home to a community of more than 400 Catholics who were severely harassed in the following two decades when their churches were destroyed and the priest's house confiscated.
A final influx of immigrants arrived during the Portugal–Maratha wars in Goa during the late 17th and early 18th centuries. Relations between the Wodeyars and the Mangalorean Catholics improved until 1717, when an anti-Christian outburst led to the expulsion of the resident priest who was thereafter forbidden to preach.
