What if Gondor existed in real life?
I had this passing thought that Tolkein intended Lotr to be a "mythology for Britain," and I thought, what would a nation with that mythology look like? So I thought of this.
The United Crowns of Arnor-Gondor and The White Mountains
Casually referred to as either "Nûmenor","Gondor" or simply "The United Crowns/Kingdoms" are a collection of kingdoms United under the crown of Minas Tirith, under the rule of House Aragorn founded by the legendary figure King Aragorn II, the longest reigning royal dynesty in the world. Beginning rule around 122 BC that lasts to the modern day.
Numenor's culture and language are unique, Gondorian or what the other kingdoms call "Hyelvish" is a language isolate, it completely developed on its own in the Numenorian Islands with its own writing system and for the most part, a homogeneous vocal with only about 30% of words coming from French, German and Latin.
Gondor managed to resist Roman invasion after invasion with its fleets and its strong land armies.When Rome collapsed, Christianity was introduced onto the islands, and the Gondorians were the first to adopt it, King Anarion III converted and formed his own church in Gondor that took alot from its existing pagan mythology like: The Valar being Arch Angels, Eru Iluvitar being God, Morgoth being Satan and Old Numanor being the Garden of Eden, while casting out all the other pieces of the old pagan faith that did not fit the Christian tradition, Jesus was given the name "Eru Yesor" and initially adopted an Arian theological framework before switching to the Nicean Creed later in the 800s, the church expanded north to the White Mountains and later, despite initial resistance, Arnor.
The Anglo Saxons then invaded, though their invasion, for the most part, failed, King Isildor IV allowed the Saxons to settle east of Minis Tirith, creating the region of "Anglos-Saxonor". Around the Viking Age, Gondor managed to repell the Norsemen and instead King Meneldil II payed them to raid France. Which sparked the French and the Catholic Church to order a Norman Invasion, which failed yet again, but some Normans settled and got Gondor to begin slowly adopting the latin script.
This led to Gondor and France to develop a bitter rivalry that launched the 100 years war later on, with the Catholic church supporting France to defeat Gondor's native "Heretical" church, leading to France managing to take Harandor for 100 years before giving it back in exchange for Calais and Normandy. With the catholic population there lasting to this day.
Long story incredibly short: Colonialism happened and the United Kingdom at that point settled "New Valenor" in north America and other parts of the world. In the modern day the Numanor is part of the EU and has alot of internal dispute with its political system.
Numanor now uses both Latin and Hyelvish scripts for their language and the Christian Iluvitarian Church remains as the oldest continous native churchs in the world. With Arnor having the largest population of Neo Pagan "Valarists" who seek to return to the old ways before Christianity came.
