Originally, there were twelve districts represented.[2]
For many years, a high property qualification ensured that the House of Assembly was dominated by the White Jamaicanplanter class. However, to elect these representatives, the bar was lower for "freeholders", who just had to be white men with a house, pen, or plantation, and owned black slaves.[3]
A law passed in 1840 allowed some blacks and mixed-race men to vote in elections to the Assembly, though they had to own property, so the white planters continued to dominate it.[4]
