South Vyvland (Vyvlander: Syfvyvlu, officially the Nationalist Republic of Vyvland, Vyvlander: Nazonalesrepublik Vyvluds) was a state occupying the southern half of present-day Vyvland. For all but three years of its existence, the country was ruled by military dictator Amiral Jeuves and his successor Erman Sanker. The country was a dictatorship governed by solely the Nationalist Movement.
South Vyvland was formed from the Kingdom of Vyvland by the Accords of Nencia, signed on the 25th March 1935 at the end of the Vyvlander Civil War. The Accords also established North Vyvland, which governed the northern half of the island, and Magane, a Vyvlander colony. Ex-naval commander Jeusev Jueves was installed as Master President and presided over a period of recuperation after the war's destruction. During this time, laws relating to the Swedes in Vyvland became much more strict, until the entire population, numbering over 200,000, was expelled in January 1945. Approximately 90,000 died, causing widespread international condemnation, including from East Luziyca, who had previously supported Jueves. However, East Luziyca would go on to open a military base at Syfmion in 1948. Economic growth began to stall due to trade embargoes and widespread domestic restrictions.
The East Luziycan Central Intelligence Agency removed Jueves and his followers from political posts during a series of coups in the 1950s, instead installing Erman Sanker. While Sanker removed some restrictions on personal liberties and began to grow the economy, the South stayed well behind the living standards in the North. The political system also remained very closeted, with the few elections held being marred by ballot-stuffing and elimination of opponents.
Sanker was assassinated in 1980, and appointed Ans Eloim as his successor. Eloim failed, however, to maintain order, leading to three years of unrest and violence, including three bombings in Lorence carried out in 1981 by Iglesian anarchist terrorist group Revolution 68. By late 1982, the situation had quietened, and a group of southern representatives began to negotiate with Abram Zymeker's government of the North for reunification. This was then achieved on the 23 June 1983, when both countries reunified.
