Strategy The below is one of many player suggested strategies for Hesse. Bear in mind, due to the dynamic nature of the game, it may unfold differently for other players.

Hesse starts in a relatively weak position in its section of the HRE, however, the player has many options to correct this through conquest.

Early strategy[edit]

First and foremost as like many other nations in the HRE, currying favors with electors and the emperor is useful for the potential election to emperor, Saxony is a good choice as is Trier. Munster is a useful ally for opening moves and should be an easy ally as they almost always start friendly to Hesse, Austria is, of course, an excellent choice as well. For rivals, the player should select Cologne, and whatever two nations have rivaled Hesse.

One thing the player should consider is developing Cassel not just for the Renaissance boost but also because once the glass producing Cassel reaches 20 development it is eligible for the Diamond District event which can boost Hesse’s economy.

First war[edit]

After securing a royal marriage and an alliance with another nation or two set aside a diplomat to fabricate a claim on either Paderborn or Westfalen. In this time build to force limit. Cologne tends to have no allies or very weak ones such as Aachen. However, if Munster does not rival Cologne or worse allies them and the player has no stronger allies they should restart. When the claim is finished DOW Cologne calling in Munster with the promise of land. As soon as the war starts immediately send two stacks to Paderborn and Westfalen before Munster can take it. Colognes army starts in Köln and thus will be delayed before reaching the war goal. Once Paderborn and Westfalen are secured stack wipe any armies and siege down Köln and any allied nations. Once you have full sieged Cologne take Westfalen and Paderborn for yourself and vassalize Cologne. Vassalizing Cologne is useful as once the liberty desire goes down you have a pocket elector and sometimes nations like Gelre will declare on Cologne and after vassalizing you can use the defensive war to call your allies and take richer provinces like Upper Guelders for reduced AE (Note that if this happens it is important Hesse themselves takes any provinces and not Cologne as this will greatly increase their liberty desire.) Munster will now most likely break the alliance, this is okay as once truce runs out you can potentially invade them for their land. Improve relations with Cologne to bring their liberty desire down.

Post first war[edit]

With this completed Hesse now has a power base they can expand in a multitude of directions with. Recommended targets for expansion include Brunswick to get closer to forming Westphalia should they ever become elector or emperor (same is true with Magdeburg should the player reach it), Munster, Cleves to connect Köln to Hesse, and Frankfurt if it loses its free city status for its higher dev and center of trade. Should the player own Guelders or a Cleven province Dutch minors like Gelre or Utrecht are also prime targets for access to a coastline and these provinces higher base tax/manpower. Hesse should also capitalize on any breakaway Dutch minors like Brabant or Holland as these rich provinces can very much boost Hesse’s development should they ever become free or Burgundy becomes weak. The player can choose to make Cologne a march for reduced Liberty Desire and so that Cologne packs more of a punch but annexing is also a suitable option should the player wish it.


The player is up to their own personal choice as to whether to stay Catholic or to convert to Protestant/Reformed but converting may be the better choice as its central location within the HRE a Center of Reformation can easily spread throughout and compliments Hesse’s historical status as a member of the Protestant League.


For first idea group the player should most likely go with either a military idea such as Quality or Quantity for stronger troops, or of course just more of them, or Diplomatic to boost Diplomatic reputation.png, diplo rep and gain more diplomats, and naturally the amazing, essential, +25% Improve relations.png. Economic is also a strong choice for the extra -20% Dev cost, and it also mixes really well with Quantity ideas for the Policy. The extra Tax, and other modifiers help too!
