evidence: During the 1870-1880’s the British survey team led by Woodthrope first entered the Northern Sangtam territory. When the Britishers asked the people about their tribe, they replied that they are the people who migrated from Sangdang (now Satami under Zunheboto District) which was their ancestral village. Thus the word Sangdang was interpreted as Sangtam by the Britishers.
