In Jamaica, there were a number of newspapers that represented the views of the white planters who owned slaves. These newspapers included titles such as the "Royal Gazette, The Diary and Kingston Daily Advertiser, Cornwall Chronicle, Cornwall Gazette", and "Jamaica Courant". In 1826, two free coloureds, Edward Jordan and Robert Osborn, founded "The Watchman", which openly campaigned for the rights of free coloureds, and became Jamaica's first anti-slavery newspaper. In 1830, the criticism of the slave-owning hierarchy was too much, and the Jamaican colonial authorities arrested Jordan, the editor, and charged him with constructive treason. However, Jordan was eventually acquitted, and he eventually became Mayor of Kingston in post-Emancipation Jamaica.
