Radovid III of Redania, also known as "the Bold" or "the Red" (for his hair color), was the great-grandson of Radovid the Great and the king of Redania. He married princess Viviana of Lyria (his first cousin). Viviana had one son, Vridank, presumably Radovid III's son.
Determined to regain the prestige accorded his great grandfather, he tried to assert Redanian sovereignty over the North. These attempts were soundly rejected by the northern rulers and led to the first treaty negotiations. During his reign there was a border scuffle with Aedirn and customs wars with Temeria, Kovir, and Kaedwen. He and Benda of Kaedwen traveled to the winter capital of Kovir, Lan Exeter, to enter into negotiations with Gedovius. By virtue of the First Treaty of Lan Exeter, he was allowed to retain the title of King of Kovir and Poviss, but only until his death.
Radovid III was an energetic and shrewd ruler. Under his rule Redania regained the rich lands of the Buina and Nimnar, regaining lands lost since the time of Vestibor, establishing the northern border on the river Braa. The dispute with Temerians for Delta of Pontar finished with a compromise declaring Free City of Novigrad. Redania's position was strengthened over the Middle Pontar, a perpetually disputed border with Aedirn. He also tried a bold war with Kovir, but to bad effect (see The Tower of the Swallow). But for Redania the greatest loss was the irreparable death of the king at the age of just 49 years. Radovid III died of meningitis caused by a tick bite.
