Wars are a way to earn gold(Euro), conquer regions for more resources, raise your military rank and have your name listed on the patriots page.
You must have attack weapons to attack and defense weapons to defend a region.
Only verified accounts can do damage in wars.
Not wearing a full set of clothes applies a 10% damage penalty in wars.
For each determined amount of damage dealt in a war, you will earn medals and gold if available in the war fund (check a war page for the damages needed, the gold that can be earned and the war fund available at the moment for the first 10 medals in each rank).
The gold earned is taxed by countries and recruits (5%).
Surplus war medals (above 10 for each rank) can be converted into collectable medals, this means if you have a rank of General, for example, you can convert any medals you win in wars into collectables. You can’t convert collectable medals back into ranking medals.
Collectable medals can be sold to the War Fund for their full value.
You can do this whenever you can/want, as long as the War Fund has the fund to buy it.
