Congress of Visegrád (1339)
The second Congress of Visegrád was a 1339 summit in Visegrád that decided that after the death of Casimir III of Poland, the son of Charles I of Hungary, Louis I of Hungary, would become King of Poland if Kazimierz did not have a son, as would happen.
When Casimir died in 1370 from an injury received while he was hunting, his nephew, King Louis I of Hungary, succeeded him as king of Poland in personal union with Hungary.
