How does it work, well governors is providing their king with tributes in form of Resources that is taxes for being a part of the kingdom and as well treasures.
Treasures is generated from stolen goods that is obtained from robbers and robber camps. When you sell those stolen gods as a governor you giving your king treasures that generates victory Points for the kingdom.
Keep in mind that treasures can as well be stolen from other kings by a succeeded attack, Each attack can only carry 33% of the kings treasures but you need to send a hero with you to do so.
When you start an account on travian kingdoms it’s important that you know if you want to be a king or a governor. The king is as it sounds a king of a kingdom and the kings jobb is to protect the governors.
So if you choise to be a governor you will be placed in a kingdom with another king.
They describe it as if you are a more experienced travian player or an active player you can pick to be a king or if you are new to the travian system you may choice to be governor.
In this case I took governor and it gave me 7 days of beginner protection and that makes me protected from attacks in a 7 days period or if I reach 200 population.
Great thing to notice is that if you pick to be a king you only have 2 days of protection and can therefore be attacked by other kings since they also only have 2 days of protection.
So pick the one you belive is the best for you.
