What Does The Great Betrayal Mean?
Every achievement in Civilization 5 is a reference to something, and this one is not without meaning.
It’s just really hard for a layman to understand exactly what it means… because everyone is always declaring something to be “The Great Betrayal” whether it’s Obama’s NSA policy, Pat Buchanan’s conservatism, or British politics.
The Great Betrayal starts off in 300 AD during the time of Constantine. Constantine named Emperor of Rome declares Christianity as the state religion of the Roman Empire.
Seeing a need to spread the religion fast he creates five centers of the religion. The most important would be Rome as the old capitol of the Roman Empire. The second most important would be Constantinople, a new city he created in modern day Istanbul, Turkey.
With the Senate and army now in Constantinople Germanic, Visogoth, Hun tribes were free to endlessly sack Rome. Rome’s star was fading and Christianity was now spreading by the hand of the Patriarch of Constantinople, not Rome. The Patriarch of Constantinople was named the Emperor of a new Byzantine Empire (also called the East Roman Empire).
While Rome was being sacked all of the people’s evacuated to form new civilizations. One group of noblemen and merchants moved to the swamplands of Venice to form the Venetian society.
700 years later Pope Innocent III declared the fourth crusade had begun. The usual suspects, England and France, were at war with each other so he had to round up a new group of soldiers. He sent couriers off to the Hinterlands of Germany, into Bulgaria, Romania, Sweden, and Venice.
The result was an army for a crusade to meet at Venice and to be lead by the majority group of Venetian merchants (who also controlled the ships).
The Venetian Merchants (lead by a blind Enrico Dandolo) found an army of 15,000…. not quite enough to Crusade Islam controlled Jerusalem.
Prince Alexos IV wanted to meet with the crusader offering assistance. His deal was to offer 300,000 silver, 10,000 troops, 500 knights and 1,000 ships. In exchange the army would have to dethrone his father Alexos III and install him.
Many crusaders continued on to Syria leaving an even smaller army left to take Constantinople. Seeing odds of 3:1 the Venetian Army was able to break through Constantinople’s wall and take the city for Alexos IV.
However Alexos III during the siege escaped the city stealing all of the gold. He installed Isaac II as Emperor before leaving. The crusaders demanded Isaac II make Alexos IV a co-Emperor thinking they might get paid.
Alexos IV’s first duty as co-Emperor is to come up with the money. He liquidated the jewelry and silverware of Constantinople and was only able to come up with 100,000 silver.
Isaac II died. With his death a nobleman, also named Alexos, saw Emperor Alexos IV as a weak ruler and saw to depose him. Alexos the merchant kills Alexos IV and makes himself Emperor Alexos V.
The crusaders demand that Alexos V keep the contract made with Alexos IV, of which he refuses. The crusaders as a response sack and pillage constantinople stealing all of the treasures, raping the women, murdering children in cold blood, knocking down all the walls and destroying the army infrastructure.
It was a battle of Christian against Christian in a Holy City. As a response Pope Innocent III excommunicated all of the Venetian crusaders. Excommunication was a papal power that made it so once done God could not hear you. This power made it so people could not confess their sins before death and thus would not go to heaven.
Post this conflict the Latin citizens of Constantinople felt deeply betrayed by Rome as the city soon fell into Muslim hands after six decades of defending Christianity from this same threat.
How to Do The Achievement
Okay so you’re bored with the story I’m guessing and want to know how it is done.
First and foremost you cannot have a religion of your own. To orchestrate this you will need to make sure never to make a religion. Every single time you get a Great Prophet you just delete it for 0 gold.
In the setup you should select Archipelago as your map type. This should be the map type you play Venice any time. This will make survival far easier and war with your neighbor far easier. Yes you will need to be peaceful with your neighbor for a while.
Next up, you will need to get your capitol all religioused up. I would recommend quickly learning sailing techs so that you can sail a very long way. You are going to want to setup trade routes with religious capitols.
Yes, religion can be traded (so can science). On the tab trade tab it will indicate what you are trading. You will want to trade in as much religious elements as possible.
You will also want to be a nice juicy capitol they will want to trade with. To do this select the Traditional policies so that your capitol city is huge.
Now you have to wait… patiently. Eventually your city will get converted by the city you are trading resources with.
Make sure to max out your trade routes and trade (from your capitol) with as many of their cities as possible to increase the amount of religion coming to your city.
As your city becomes more religious and gets more religious followers begin building up an army. The Venetian Galleass are a very potent melee ship which you should have a few in your army for knocking out armies at sea and attacking the enemy capitol.
Once your capitol becomes of another faith, attack that cities capitol.
Easy peasy lemon squeezy!
