The answer may lie hidden and buried deep inside North Canara in Karnataka. To say that East African came to Goa is an understatement. In fact, majority of East Africans were brought to Goa as slaves. To understand we have to go back 6th or 7th century when Arabs took control of Swahili Coast(much of East Africa), and captured Bantu (Janz)people to be traded as slaves to Persian Gulf and as far away as to China and India. Ostensibly, slave trade from the East African coast to Goa existed long before Portuguese and English mastered it. Much changed after the slavery was abolished by Indian Slavery Act of 1843. Fearing for their safety, the Bantus in Goa, took refuge deep in the jungles bordering Goa. In some villages in Goa, the Bantus were colloquially referred to as "Habshis". Nowadays, the Bantu people are known as "Siddis". The Siddis of Goa are mainly concentrated in Uttara Kanada and till today speak in Konkani.
