My example.
"The first ever known history of the Aegeans dated back to 255 B.C.E and begins with the Nomadic people of Greece constituting a small trading port city on the island of Lemnos or Lemonia, that traded clay goods and glassware with the nearby Greeks and Romans.
The Mediterranean Kingdom of Lemonia first came known in the year 122 B.C.E when a Nomadic King, King Aegean Agulma, conquered the small trading port city and sought to build a Kingdom. Many War with the Romans, Greeks, and nearby Aegeans came and pasted, but Agulma's kingdom stood the test of time. He conquered the Isles of Byzantium (Aegean islands), casting both the Greeks and Romans from them in 113 B.C.E.
After the dust had settled the King sought to form a Grand Kingdom that would be later called Agulma (Old Lemnosian for Aegean). He took the islands of Lemnos, Agios-Efstratios, Samothrace, Samos, Icaria, Patmos, Samos, Karpathos, Tinos, Andros, Sporade, Thasos, Imbros, Tenedos along with many, many more, for his people. He built his great Capital city of Myr which means "Home" in Old Aegean (That would become Myrina later or "Home to all") on his main island Limnos or Lemnos. He later renamed himself Lord of the Aegeans for he had united the Aegean islands under his banner, the Green, white and Gold.
Although his Kingdom would crumble under the weight of the war from the Romans, Greeks and local unrest and would later became part of the Eastern Roman Empire then later Greece.
The Kingdom was disbanded.. until recent times."
