The moment that could have changed it all

Heritage Malta is set to breathe life into one of the most gripping chapters of Maltese history with the launch of a new immersive exhibition titled ‘Betrayal and Vengeance: The Slaves’ Conspiracy of 1749 in 19 Historical Drawings’.
Opening at the Inquisitor’s Palace and the National Museum of Ethnography this September, the exhibition marks the 275th anniversary of the infamous Slaves’ Conspiracy, an event that could have dramatically altered the course of Maltese history.
This exhibition promises to be a deep dive into the events of the failed revolt of 1749, a time when Malta, under the rule of the Knights Hospitaller, faced a dramatic and potentially catastrophic challenge from within. The plot, conceived by Muslim slaves, aimed to assassinate Grand Master Manuel Pinto da Fonseca and seize control of the island. While the rebellion was ultimately thwarted, the echoes of this daring plan still resonate through the annals of Maltese history.
At the heart of the exhibition are 19 meticulously restored drawings that depict the intense and often brutal aftermath of the conspiracy. These rare illustrations, recently restored by Heritage Malta, will serve as the centrepiece of a narrative that explores the political, social, and cultural dynamics of 18th-century Malta. Through these drawings, visitors will be transported back in time, bearing witness to the drama that unfolded following the arrival of the mutinous Ottoman galley, Lupa of Rhodes, at the Grand Harbour on 2nd February 1748.
The galley, commandeered by enslaved Hungarians, Georgians, and Maltese, brought with it over 150 Ottoman prisoners, including Mustafà, the Pasha of Rhodes. This daring act of rebellion set the stage for a larger conspiracy, with Mustafà himself at the helm. His ultimate goal? A widespread revolt that would see Malta fall into Ottoman hands.

A tale of treachery and turmoil
The exhibition doesn’t just recount the conspiracy itself but sheds light on the complex world of 18th-century Malta, where power, diplomacy, and betrayal were in constant play. Visitors will explore how Mustafà, after his initial capture, was allowed to remain in Malta under house arrest due to the Franco-Ottoman alliance, and how he subsequently converted to Christianity and married a Maltese woman. These unexpected twists add layers to the story, revealing the intricate relationships between the East and the West during this tumultuous period.
The central plot, which was slated to unfold on 29th June 1749 during the feast of Saints Peter and Paul, involved a meticulously planned uprising. The slaves intended to poison the banquet at the Grandmaster’s Palace in Valletta, assassinate the Grand Master in his sleep, and ignite a revolt that would have seen Malta overrun by an Ottoman fleet waiting to strike. However, a chance quarrel in a coffee shop led to the plot’s discovery three weeks before its planned execution, sealing the fate of the conspirators.

The exhibition features a collection of historical documents, including news sheets exchanged between Inquisitor Paolo Passionei and the Vatican, as well as contemporary reports and sermon sheets, providing rich context for the era. These artefacts allow visitors to delve into the broader themes of power, diplomacy, and treason that shaped this period, offering a comprehensive understanding of the conspiracy and its lasting impact on Maltese history.
Practicalities
Entrance to the exhibition will be included in the Inquisitor’s Palace and the National Museum of Ethnography experience. However, it’s worth noting that, due to the historic nature of the building, persons with impaired mobility may find access to certain areas challenging.
As you prepare to step back in time and uncover the secrets of the 1749 slaves’ conspiracy, remember that this exhibition is not just a retelling of history — it’s an exploration of the fragile threads that hold societies together and how, in the blink of an eye, they can disentangle.
