Bornean Wars (Fidem Pacis)

The Bornean Wars were a series of conflicts fought between European expeditions from Albion, France and Aquitaine, each trying to conquer and colonise the island for their respective country, and the native states of Brunei and Lanfang. Throughout the 19th century the great European powers expanded rapidly overseas, overcoming Cambodia, Siam, Malaya, Sumatra, Java and Sulawesi, until only Borneo was left of the independent countries of south-east Asia.

By this point China was greatly concerned about its loss of influence in the area, which had formerly paid tribute. When in 1824 Albion issued an ultimatum to Brunei concerning some minor trade disputes, the latter appealed for assistance from all its neighbours. By the time Albion actually invaded and occupied the Bruneian capital, naval  convoys full of money and weapons were already on their way from China, and half of the Lanfang army was marching along the coast to help.

With the extra help, the remaining Bruneian troops were able to besiege Bandar Brunei and ultimately drive Albion out. Although Albion would invade several more times over the following decades, as well as French and Aquitainian incursions, it was never able to control the whole island and was always eventually forced to retreat.
