Dithmarschen is a member state of the Holy Roman Empire situated in the far north of the Empire. It starts as an independent one province nation bordering Holstein to the north and east, and Hamburg to the south. Dithmarschen has the unique republican government type of "Peasant Republic" and exists from the game start at 1444 to 1559, after which it becomes a part of Denmark. It is capable of forming Westphalia and Hanover in addition to Germany.
This section may contain outdated information that is inaccurate for the current version of the game. The last version it was verified as up to date for was 1.25.
Dithmarschen starts in a difficult position with few expansion opportunities. Its neighbor to the north, Denmark, is far too strong to expand into early on. Other attractive expansion targets such as Hamburg or Lubeck quickly become free cities (protected by the emperor) or part of a trade league. Expansion is further hampered by increased aggressive expansion within the HRE, and as such will have to be slow and deliberate. Additionally, unless an alliance with the emperor is secured, demands for unlawful territory are likely and may lead to an attack by the emperor.
An ideal first target is East Frisia, which is the only small country nearby that can be attacked and that is not in the empire (thus no unlawful territory). Taking it will allow fabricating on more countries in the area as well. Saxe-Lauenburg may also be feasible, depending on alliance situations. It is important to note that speed of attack and military access play very important roles in the early game - the player may easily defeat two countries on their own, if they can overpower the first target without the second target being able to intervene in time.
Developing provinces may be beneficial to both strengthen the economy and trade power, and to spawn institutions if needed.
Initial alliances should be based on the player's rivals, and an alliance and high relations with the emperor (likely Austria) should be sought as soon as possible to avoid demands for unlawful territory and/or being declared war upon with the Imperial Liberation casus belli. As a republic, Dithmarschen is unable to form royal marriages, which makes it a little more difficult to build and keep alliances with bigger nations. It may also be beneficial to join a trade league in the beginning for defensive purposes.
Once Dithmarschen has grown into a regional power, it should be time to take on Denmark, ideally with the help of their rivals (likely to include England, Poland or Muscovy). It is also beneficial to support the independence of Sweden in order to both weaken Denmark significantly and to allow controlling Sweden's growth (in case the player is going for the "Lessons of Hemmingstedt" achievement). Further expansion should be in northern Germany and further to the south and east if feasible, and may even include Dutch territories - however, the player needs to be aware of the Dutch revolts happening between 1550 and 1650 with large and recurring rebel armies. This can be avoided by changing the culture of conquered Dutch provinces before 1550, or waiting with conquering until after 1650.
The player may form Westphalia; this requires becoming an elector, a prerequisite for which is being a monarchy, thus having to abandon the unique Peasant's Republic.
- Due to its position in one of the richest trade nodes in the world, taking Trade ideas can be very beneficial.
- Diplomatic ideas or Espionage ideas can help manage aggressive expansion in the HRE
- Military ideas such as Defensive ideas or Quality ideas stack well with Dithmarschen's national ideas
- Humanist ideas can help with religious intolerance once the reformation hits.
- Economic ideas can help to further boost national income
