Happiness  

The statistics showing how satisfied with the sovereign’s rule the population is. There are many factors - daily or single time, which cause increase or drop of the current happiness. These effects should be considered carefully so no unexpected unpleasant results occur. The main consequence from low happiness (not recommended) is emigration, riots and rebellions. The closer to its maximum the happiness of a province/colony is, the happier the population will be and respectively - the smaller the chance for emigration and riots.

Happiness balance  

The overall sum of all local or global daily happiness modifiers for the current 24 hours between two migrations. The happiness balance is the statistic determining if the Happiness will be rising or dropping every minute. It is calculated over a 24 hour period, i.e. if the Happiness balance is +24/24h, 1 Happiness point will be added to the current happiness value every hour. The happiness balance is showed in green in the left wing of Happiness window.

Holidays protection  

An option that can be activated by every player but only during holidays previously announced by Imperia Online team and for limited periods determined by Imperia Online. While activated, the account cannot be attacked neither can send attacks. Army cannot be sent to Evasion. Meanwhile, the account can be accessed, Buildings can be constructed, Technologies can be researched, army can be recruited etc. All attacks sent to the respective Empire before the activation will still be performed. Alliance battles do not fall under any rules of protection whatsoever. Attacks to independent cities for pillaging resources, attacks on barbarian camps are also not possible. Attacks on the Dark fortress, Skull of wonders, Tower of Knowledge and Stone Prison are possible. Army upkeep will not be taken although it will look as if it is taken in Statistics menu (army upkeep will be taken in case you attack the Dark fortress, the Skull of wonders, Tower of Knowledge or Stone Prisonthough).

* Both, Vacation mode and Holidays protection, can be activated solely if you currently don't have troops on a mission, except evasion and movement between holdings. Please, note that army upkeep will be taken on evasion and movement mission during a vacation mode.

Homeless Population  

Homeless is the population that gathers upon having already reached the population limit allowed by the current level of Houses. Homeless population growth is twice lower. It can be recruited for army, but cannot be hired in the mines and, thus, doesn’t produce resources. To make use of it, you should build enough levels of Houses.

Honor  

The statistics that shows each player's military behavior - whether he/she conducts equal battles and fights in a rather civilized way. Honor is earned in battles with active players but not unless the following requirements are fulfilled: losing at least 10% of your own army's units and attacking within the allowed x2 range. All players receive +2 daily Honor points and Diplomacy Officers +1 additional Honor point every day. Honor is lost upon performing pillages, attacks out of range and recalling your army 15 minutes or more after it was sent. Positive and negative Honor influence the army morale and the happiness of your empire.

NB! Honor penalty for pillaging is taken after the battle finishes and, thus, it is shown in the battle report. Honor penalty for attacking out of range, though, is taken right after the attack has been sent, so it is never shown in the battle report and Honor is always subtracted even if the attack is recalled.

Hostility  

This standing allows war declaration without any consequences to the Honor. Hostility is active right after its declaration.

Houses  

Buildings civilian villagers live in. Their levels increase the population limit of a province.
