Most migrants were people from the lower economic strata who had been left out of government and economic jobs; their lands had been confiscated due to heavy taxation under the Portuguese in Goa. As a consequence of the wealth and privileges which these Goan migrants enjoyed in Mangalore, they began feeling superior to their landless kindred in Goa. Their captivity at Seringapatam (1784–1799), where many died, were killed, or were forcibly converted to Islam, led to the formation of a separate and common Mangalorean Catholic cultural identity among members of the group, who hitherto had considered themselves an extension of the larger Goan Catholic community. They no longer self-identified as Goan Catholics. After their years of captivity, prosperity under the British and under Italian Jesuits, followed by migration for employment to Bombay, Calcutta, Poona, the Persian Gulf Arab states, and the English-speaking world, enabled the community to restore their identity. The overwhelming majority of Mangalorean Catholics are of Goud Saraswat Brahmin lineage. Historian Alan Machado Prabhu estimates that almost 95 per cent of Mangalorean Catholics have Goan origins.
