The First Sicilian War lasted from 2004 until 2006, when Sicily conquered Sardinia and Tunisia, as well as attacking the Pais de Oro. Eventually, a western coalition forced them out of Pais de Oro territory, and, with them unwilling to go further, eventually resulting in an acknowledgment by these powers of Sicilian control over Tunisia and Sardinia - but not acknowledging it, or the Italian mainland, as belonging to them. This eventually led to the founding of the Atlantic Defense Organization.
