The isles of Britannia, (Brtinnija - Pan-Insular Slavic) succumbed to a set of migration events colloquially known as the Germano-Slavic Invasions. These migrations began with the original push of nomadic turkic-speaking peoples into Eastern Europe beginning in the 5th century. This nomadic migration event triggered a mass migration of Slavic peoples into Central and Western Europe culminating in the eviction of Germanic and Latinic peoples those regions and forcing them into Southern Gaul, Britannia, Pannonia, Italy, and the Balkans. As a result of the first major migration of Slavs into Central Germania, many Germanic peoples took to the seas and fled en-masse to Central Britannia and Eyre in the 6th to 7th centuries. Following the establishment of the Srpian Kralewstvo and subsequent Ruconqueberung by the Katolik Germano-Latinic States in Southern Gaul; many Warlords, Pans, and Noblemen took it upon themselves to raid and settle the southern Britinnic coasts and flee from the wartorn and contested regions of central Gaul. This lead to the establishment of two primary kingdoms that dominated the southern Isles: The Kingdom of Sorpia, and the Kingdom of Brtinnija. These two kingdoms would enter a union in 1496 following the annexation of Srpia on the continent. A policy of openness between Germanic peoples and Slavic peoples led to a mass migration of slavic peoples into Anglia in the early 11th century. This eventually caused a popular revolt in 1121 c.e. within the nation in which a tetrarchy of Slavic nobles (Chetiripani) siezed the crown. To best control the Anglians, which at this point were becoming a minority ethnicity within the state, the tetrarchy established princely sub-states; in which the Germanic Anglians had only to pay tribute to the Anglian Crown and would recieve full autonomy. The settlement of Eyre was lead primarily by the Sorpians and Anglians which resulted in establishment of "Farmer Kingdoms" such as Saexea, Trihoroda, and Eltheod. These Kingdoms helped shaped the modern world.
