The Bukoian invasion of Sallia took place from December 1180, when Bukoian forces established a beachhead on the coast of the Sallian kingdom of Doodenelle, to May 1187, when the final Sallian kingdom surrendered to Bukoian forces. The invasion had initially been approved by Pope Alexander III in 1179, when King Edward III of Bukoia submitted his plans of invasion to him. The invasion was a major event in Sallian history, beginning over 700 years of Bukoian rule over Sallia.

In December 1180, after years of planning, King Edward III of Bukoia authorised the Bukoian navy to cross the Sea of Sallia and invade and occupy the Kingdom of Doodenelle. Doodenelle surrendered within days, and Edward authorised the invasion of neighbouring Sallian kingdoms. The invasions were personally organised by Edward. Edward attempt to rally up support in Sallia by offering those sympathetic to the Bukoians land after the war.

In 1182, the Kingdom of Dunian was decisively defeated by the Bukoians in the Battle of Dumport, and surrendered. In response, the remaining Sallian kingdoms formed a coalition, and, led by Charles George, besieged Carper. After forcing the Bukoians to surrender at Carper, they attacked Bukoian territory in Sallia, and managed to reoccupy most of the territory which the Bukoians had taken during the invasion. However, they failed to capture the key port of Newport from the Bukoians.

In January 1183, after hearing of the Sallian counteroffensive, King Edward sailed across the Sea of Sallia with a large army and landed at the town of Kenham, 6 miles away from the large city of Sandy. Edward's army decisively defeated the Sallians in the Battle of Sandy, and managed to regain all of territory lost to the counteroffensive. After beginning to push back the Sallian coalition, Edward formed the Dukedom of Doodenelle, a short-lived client state of the Kingdom of Bukoia.

Edward left Sallia in May 1183 after his army stabilised the situation, but fighting continued between the Bukoians and the Sallians. By 1186, only a single Sallian kingdom, the Kingdom of Pom, remained, and Edward largely spent most of his time authorising his army to suppress rebellions and revolutions against Bukoian rule. In April 1187, Pom sued for peace, and Edward began drafting the Treaty of Swington.

On 12 May 1187, delegations from both the Kingdom of Bukoia and the Kingdom of Pom signed the Treaty of Swington, which dissolved the Sallian kingdoms (including Pom) and formed the Dukedom of Sallia, a vassal state of the Kingdom of Bukoia, which would be administered directly from Swington, with King Edward as the Duke of Sallia.
