The Conspiracy of the Slaves in Malta is discovered.
The Conspiracy of the Slaves, also known as the Revolt of the Slaves, was a failed plot by Muslim slaves in Hospitaller-ruled Malta to rebel, assassinate Grand Master Manuel Pinto da Fonseca and take over the island. The revolt was to have taken place on 29 June 1749, but plans were leaked to the Order before it began, and the plotters were arrested and most were later executed.
The plot was discovered on 6 June, three weeks before it was to take place. Three slaves had met in a coffee shop in Valletta to win the support of a Maltese guard to the Grand Master, and began to quarrel. The shop owner, a neophyte called Giuseppe Cohen, overheard them mention the revolt and reported this information to the Grand Master. The three slaves were arrested, and they revealed details of the plan after being tortured.
The leaders were subsequently arrested, and 38 of them were tried and executed. Some plotters reportedly converted and asked to be baptized just before being killed. 125 others were hanged in Palace Square in Valletta, while 8 were branded with the letter R on their forehead, and were condemned to the galleys for life. On the insistence of France, Mustafa Pasha, who was behind the revolt, was not executed but was taken back to Rhodes on a French vessel.
