The Natestian War was the first phase of the Anglyo-Dascunyan Longerathian Wars. It lasted from 427 BP, when Natestus III, Emperor of Estontetso, invaded Dascunya, to 392 BP with the Estontetsan capture of Saint Hughes and the signing of the Treaty of Axbourne. The phase was named after the Emperor of Estonteso, Natestus III, who hoped to dismantle the large Anglyodascunyan Kingdom.
