A New Crown Colony and Government Disputes

After the Jamaican Assembly had voted for its own expulsion, Parliament made Jamaica a Crown Colony starting in 1866.(A) Jamaica's new governor, Sir John Peter Grant now held the only executive or legislative power on the island.Grant established a police force, a new judicial system, medical service, a public works department, and a government savings bank to reorganize the island.(A)He also made local 'magistrates' and improved schools to better the community. 
Also, during this time, Jamaica's economy no longer depended on sugar exports. After the 19th century, Captain A.W. Baker founded a group that would later be known as the 'United Fruit Company' and started Jamaica's trade of bananas. Bananas were soon known as the main export crop all over Jamaica.(A)
However, in the 1920's-1930's, the Great Depression brought on dissatisfied feelings regarding the Crown Colony system.(A) Rioting began in 1938 and labour unions were established for the first time, linking to political parties. Next, a Constitution in 1994 made a House of Representatives for the first time on the island and established a Legislative Council.(E) This constitution, later changed in 1953 to allow government ministers, helped Jamaica get full self-government two years later. 
In 1958, Jamaica became the founder of the West Indies Federation (a group of Caribbean islands formed in the Commonwealth)causing an even bigger influx of self-government.(A,D) Norman Manley elected as 'premier' in 1959 then dealt with resistance from Sir Alexander Bustamante. Bustamante wanted to pull out of the federation, and after a vote in 1961, the country agreed. Bustamante became premier in 1962, and the federation was discontinued.
