The Norman conquest of Sicily was a transformative period that reshaped the island's political, social, and cultural landscape. The Normans, originally of Viking descent, had settled in northern France and became known for their military prowess and adaptability. By the 11th century, ambitious Norman adventurers turned their attention to southern Italy, seeking wealth and power. Among them, the Hauteville family played a crucial role in the conquest of Sicily, led by Robert Guiscard and his younger brother Roger.

The campaign to seize Sicily from Muslim control began in 1061, as the Normans took advantage of internal divisions among the island's Muslim rulers. At the time, Sicily was a prosperous and diverse society, ruled by various Arab and Berber factions who had governed the island for over two centuries. Despite their dominance, infighting among the Muslim emirs weakened their hold, providing the Normans with an opportunity to launch a well-planned invasion. Robert Guiscard and Roger initially captured the strategic town of Messina, using it as a foothold for further expansion. Over the next three decades, the Normans steadily advanced across the island, engaging in fierce battles and sieges.

One of the most significant victories came in 1072 when the Normans captured the capital city of Palermo, a major cultural and economic center. Palermo's fall marked a turning point in the conquest, as it solidified Norman authority in the region. However, complete control of Sicily was not achieved until 1091 when Roger seized Noto, the last stronghold of Muslim resistance. With this final victory, the Normans established their rule over the entire island, bringing an end to Muslim governance while incorporating many aspects of its administrative and cultural systems.
