under pressure from the united states government, the brothertown indians, together with the stockbridge-munsee and some oneida, removed to wisconsin in the 1830s, taking ships through the great lakes. in 1839 they were the first tribe of native americans in the united states to accept united states citizenship and allotment of their communal land to individual households, in order to prevent another removal further west. most of the neighboring oneida and many of the lenape (delaware) were removed to indian territory (present-day oklahoma) in this period.
