The British administration, which began with Sir Robert Farquhar as its first governor, oversaw rapid social and economic changes. However, it was tainted by the Ratsitatane episode. Ratsitatane, nephew of King Radama of Madagascar, was brought to Mauritius as a political prisoner. He managed to escape from prison and plotted a rebellion that would free the island's slaves. He was betrayed by his associate Laizaf and was caught by a group of militiamen led by Franco-Mauritian lawyer Adrien d'Épinay and summarily executed. He was beheaded at Plaine Verte on 15 April 1822, and his head was displayed as a deterrent against possible slave rebellions.
