Harald Hardrada

Harald Hardrada fought at the Battle of Stiklestad at age 15, supporting his half-brother Olaf II. The battle ended in defeat and Olaf's death, forcing Harald into exile. This event shaped his later ambition to reclaim power in Norway.

After Stiklestad, Harald Hardrada traveled to Constantinople and served as a commander in the Varangian Guard of the Byzantine Empire. He fought in campaigns in the Mediterranean, Sicily, and the Balkans, amassing wealth and military experience.

Harald Hardrada returned to Scandinavia and claimed the Norwegian throne, initially co-ruling with Magnus the Good. After Magnus's death in 1047, Harald became sole king of Norway, ruling until 1066. His reign was marked by centralization and conflict with Denmark.

Harald Hardrada launched a prolonged war against Sweyn Estridsson of Denmark, seeking to reclaim the Danish throne. The conflict lasted for years with raids and battles, but Harald failed to conquer Denmark, eventually making peace in 1064.

Harald Hardrada invaded England in September 1066, claiming the English throne. He was defeated and killed by King Harold Godwinson's forces at the Battle of Stamford Bridge. His death marked the end of the Viking Age and the last major Viking invasion of England.
