Chandragupta II
Chandragupta II (Gupta script: "Cha-ndra-gu-pta", r.), also known by his title Vikramaditya, was one of the most powerful emperors of the Gupta Empire in northern India.
Chandragupta continued the expansionist policy of his father Samudragupta: historical evidence suggests that he defeated the Western Kshatrapas, and extended the Gupta empire from the Indus River in the west to the Bengal region in the east, and from the Himalayan foothills in the north to the Narmada River in the south.
His daughter Prabhavatigupta was a queen of the southern Vakataka kingdom, and he may have had influence in the Vakataka territory during her regency.
The Gupta empire reached its zenith during the rule of Chandragupta.
Chinese pilgrim Faxian, who visited India during his reign, suggests that he ruled over a peaceful and prosperous kingdom.
The legendary figure of Vikramaditya is probably based on Chandragupta II (among other kings), and the noted Sanskrit poet Kalidasa may have been his court poet.

Eystein Glumra
Eystein Glumra(" Eystein the Noisy" or" Eystein the Clatterer"; Modern Norwegian" Øystein Glumra") also known as Eystein Ivarsson, was reputedly a petty king on the west coast of Norway, during the 9th Century.
The" Heimskringla" saga states that Eystein Glumra was the father of Rognvald Eysteinsson and Sigurd Eysteinsson:" The first earl in the Orkney Islands was called Sigurd, who was a son of Eystein Glumra, and brother of Ragnvald earl of More.
After Sigurd, his son Guthorm was earl for one year.
After him Torf- Einar, a son of Ragnvald, took the earldom, and was long earl, and was a man of great power".
According to the" Orkneyinga Saga", Eystein Glumra was the son of Ivar the jarl of Uplanders and grandson of Halfdan the Old.
" Orkneyinga Saga" also named Eystein Glumra as the father of Rognvald Eysteinsson:" Heiti, Gorr ’s son, was father of Sveiði the sea-king,[ who was] the father of Halfdan the old,[ who was] the father of Ivar the Uplanders ’ earl,[ who was] the father of Eystein the noisy,[ who was] the father of earl Rognvald the mighty and wise in council".

Ramagupta
Ramagupta (IAST: Rāma-gupta; r. c. late 4th century CE), according to the Sanskrit play "Devichandraguptam", was an emperor of the Gupta dynasty of northern India.
The surviving fragments of the play, combined with other literary evidence, suggest that he agreed to surrender his wife Dhruvadevi to a Shaka enemy:
However, his brother Chandragupta II killed the Shaka enemy, and later dethroned him, marrying Dhruvadevi.
The official Gupta genealogy does not mention Ramagupta, and therefore, the historicity of the "Devichandraguptam" narrative is debated.
Several other sources refer to the events mentioned in the play, but these sources do not mention Ramagupta by name, and may be based on the play itself.
Three undated inscriptions, written in a variety of the Gupta script and discovered in central India, mention a king called Ramagupta: this seems to attest the existence of a Gupta emperor named Ramagupta, although it does not conclusively prove the historicity of the "Devichandraguptam" story.
Some coins discovered in central India have also been attributed to Ramagupta, but this attribution has not been unanimously accepted by modern historians.
