"In 1834, the sons and daughters of Africa who had been kidnapped and forced into labor were set free throughout the British Empire and, in 1838, Dominica became the first British Caribbean colony with a legislature controlled by a black majority.
In 1896, the United Kingdom took back governmental control of Dominica, when it became a Crown Colony.
On November 3, 1978, Dominica became an independent nation with a population of around 70,000.
