Thangata is a word deriving from the Chewa language of Malawi which has changed its meaning several times, although all meanings relate to agriculture. Its original, pre-colonial usage related to reciprocal help given in neighbours' fields or freely-given agricultural labour as thanks for a benefit. In colonial times, between 1891 and 1962, it generally meant agricultural labour given in lieu of a cash rent, and generally without any payment, by a tenant on an estate owned by a European. Thangata was often exploited, and tenants could be forced to work on the owners' crops for four to six months annually when they could have cultivated their own crops. From the 1920s, the name thangata was extended to situations where tenants were given seeds to grow set quotas of designated crops instead
