In 1865, after much agitation and tension, the colonial office replaced the elective assembly with one made up of one-half members who were elected and one-half who were appointed. Planters, who were allied with colonial administrators, outmanoeuvred the elected legislators on many occasions. In 1871, Dominica became part of the British Leeward Islands. The political power of the ethnic African population progressively eroded. Crown colony government was re-established in 1896. All political rights were curtailed for people of colour and blacks, who were the overwhelming majority of the population. Development aid, offered as compensation for disfranchisement, resulted in negligible improvements in conditions for most ethnic Africans.
