Influence, appearing in Anno 1800 as Influence, is a special resource which can be invested to increase the power of one's empire. Influence can be used in a variety of ways such as spreading propaganda, constructing ships, settling additional islands, buying shares of a competitor's islands etc. Influence can be gained by amassing a large population, awarding influence points for reaching next profile levels, based on global population. Attracting Investors Investors to your empire by upgrading engineer residences to investor residences also increases your influence pool for each residence upgraded. The amount of influence generated depends on the difficulty setting of influence:

  • easy: 20Influence per profile level, 3Influence per investor residence
  • medium: 15Influence per profile level, 2Influence per investor residence
  • hard: 12Influence per profile level, 1Influence per investor residence

Example 1

You have 8 schooners, each cost 1 influence so you meet the exact limit of 8 points, your trade fleet costs no influence. Constructing another schooner will lower your available influence pool by 1 point. If you have no influence points available, you can’t construct any trade ships. To continue developing your trade fleet you need to either free up your influence from another category (for example by destroying or selling some military ships) or gain more population, or build more investor residences.

Example 2

If you have 10 schooners and 2 charter routes you can’t construct more trade ships for free, but you can create one more charter route – even though it’s within the same category, trade ships and charter routes are different subcategories with separate limits.

Using influence

To use influence you don’t have to perform any special actions. When you reach the limit, your influence points will be automatically invested if you override the limit. For instance when having 8 schooners, to invest your influence into trade ships subcategory you just have to construct or buy a trade ship and respectable amount of influence points will be immediately deducted from your pool.

Freeing up influence points

All invested influence points can be received back if you get rid of corresponding investments. Destroying excess ships, optimisation buildings, zoo, museum or botanical modules, losing islands, shares or having a new newspaper issue – all this actions or events free up influence points which you have previously invested.

Gaining more influence

To gain more influence points you need to expand your population or upgrade more engineer residences to investor residences. At the start of the game you have a base influence pool of 100 points. Until reaching 16000 people, every 400 people living in your empire increase your pool by the amount of points that depends on your influence difficulty setting. After reaching 16000 of global population, the number of people required to increase your influence increases exponentially - see: profile level. Additionally, every investor residence will grant you more influence points.

Investment in one category

Investing lots of influence points in one category grants a buff connected to that category. You can get one big buff from one category or several smaller buffs from several different categories. These bonuses are global and affect your entire empire. Investment in one category also grants you a special title. The list of all bonuses is displayed in the table below.
