700 ALB: Since time immemorial, Griffons have fought for wealth and power, with no king or country strong enough to unite the others.

However, in 705 ALB, Grover, King of Flag of Griffonstone  Griffonstone used the Idol of Boreas, an artifact of incredible power, to defeat the two most powerful Kingdoms on Griffonia - Flag of Kingdom of Wingbardy  Wingbardy and Flag of Kingdom of Aquileia  Aquileia. After their submission, Grover claimed the title of Kaiser, or Emperor, which quickly prompted the rest of the continent to bend the knee. Grover I, as he would become known, had achieved the impossible and united the griffons under a single leader, creating a dynasty that would last 300 years.

However, Grover’s conquests were not over. He moved the capital to Griffenheim, a key position on the convergence of the Griffking river, and began looking North. When it became clear that Albert Plumenjar, the Duke of Flag of Griffonian Republic  Cloudbury, was in a vital position to unite the Northern duchies, Grover I supported him with arms. In 713 ALB, When Albert finally united the duchies in a short and decisive war, he bent the knee to Grover, leading to a mutually beneficial relationship that would leave the Empire with control over the North and a stepping stone into the Flag of Kingdom of Vedina  Kingdom of Vedina.

After his early conquests, Grover continued to secure the Griffonian continent for another 70 years. In 728 ALB, Grover founded the University of Flag of Free City of Romau  Romau, a beacon of higher learning that attracted more and more griffons to his new Empire in search of a greater future. In later years, Romau would become a prosperous Imperial free city, and the University would continue to attract the sharpest minds in Griffonia. In 747 ALB, Grover crossed the Creeper Mountains, beginning his decisive Eastern campaign, where he crushed the Flag of Principality of Lushi  Principality of Lushi and associated Flag of Kingdom of Brodfeld  Prywhenian principalities.

Then, Grover moved into the lands of the Minotaurs, seizing their coastal states and creating the Flag of County of Cyanolisia  County of Cyanolisia. Grover I’s ambitions were not sated, and so he moved further east. The Zaphzian cossacks were reformed into the Flag of Gryphian Host  Gryphian Host, a loyal march to the Empire, and 4 years later, Grover I’s mercenaries sacked Flag of Lake City  Jezeragrad, his first main attack against pony forces in the East. In 783 ALB, Grover I founded Nova Griffonia on the continent of Equus, beginning his first Equusian conflict against the Flag of Polar Bear Communities  Polar Bear and Flag of Kingdom of Pingland  Penguin natives.

GLOVER II "The Warmonger"

790 ALB: In 785 ALB, Grover I died. Grover II, the new Emperor, was met with much skepticism from the Griffonian populace, especially the particularly rebellious Kingdom of Aquilea, which rebelled against Grover only a day after his coronation. At the same time, forces led by the ponies faunus of Flag of Nimbusia  Nimbusia invaded the Gryphian Host, seeking to undo the efforts of Grover I’s eastern campaigns.

However, Grover II was much more of a capable commander than his enemies believed. He crushed the Aquilean rebellion and left most of the country in ashes as his feudal Imperial Army marched through the Aquilean countryside. Rumor has it he beat the Aquilean king to death with his own claws and took his third child, Giselda Discret as his bride, marrying her in the Aquilean Temple of Arcturius, which was a ruin due to Grover II’s brutal war. Despite the circumstances surrounding their marriage, Giselda proved to be a capable wife, and while Grover II was out on his conquests, Giselda Discret made his enemies disappear.

Shortly after that, the armies of Nimbusia were crushed, and Grover II solidified himself as a capable military leader and Emperor.

Grover II.

Grover II, occupied with administration of the empire, passed rulership of Griffonstone and the Idol of Boreas to his brother Guto, who faithfully guarded it. This arrangement split the family, creating two royal lines descended from Grover II and Guto.

Grover II, after his early military victories, would begin a campaign in the East that surpassed his fathers. He took over Flag of Republic of Asterion  Asterion, subjugated Flag of Sicameon  Sicameon, and sanctioned the first Eternal Crusades against the Eastern faunus ponies. These crusades consumed the next 40 years of his reign, and he died in one of them against a simple Nimbusian foot soldier.

GROVER III, The Unifier

854-914: It is said that while Grover I and II conquered the Empire, Grover III truly made it whole.

Grover III is credited for the stabilization of the Empire following the numerous wars in the East and South. The new Emperor established and revitalized a strong, centralized Imperial army, ensured the loyalty of his new subject lords, who had begun to grow angry and weary at Herzlander rule. Largely considered to be one of the best Grovers, Grover III was scarred from his father's military experiences at a young age and began a prosperous and peaceful reign - although many who disagreed with him or grew too powerful were simply disposed of...

In 854, on the year of his coronation, Grover III restored democratic rights in Sicameon on the condition that they pledged full loyalty to the Empire - but in 862, he murdered Kihai de Kissau, the first Prince to unify both Brodfeld and Sydia, who was growing too powerful for the Empire's tastes. Perhaps it could be said that these were his only major foreign policy adventures before his death in 914, after sixty years of peace, prosperity, and Imperial glory.

GROVER IV "The Glutton"

910-970: Historians are deeply divided on their views about Grover IV, the fourth Emperor of all Griffons.

His supporters believe his reign to be a continuation of the peace and prosperity of Grover III's, with the Empire largely staying out of foreign conflicts and participating in industrial and social reforms. He was an extremely competent administrator who expanded the centralization and modernization policies of his predecessor. He was adored by the commoners for his expansive reforms of the Imperial economic system, and was believed to have halted major Republican revolution efforts until, his supporters say, the corrupt administration of Grover V reverted his reforms.

His critics view him as the Emperor that destroyed the Empire and begun its downward spiral into decay and revolution. He was socially inept and utterly uncharismatic, and the nobles despised him for his pro-commoner and anti-nobility reforms. He was a glutton and famously loved chocolate, and historians generally agree that this is what led to his stroke and death in 970 ALB. He was known to be brutally honest, so much so that he had almost no allies among the nobility.

However history may speak of Grover IV, all agree he died in 970 ALB - and that was one of the acts that truly shattered the Empire.
