- Enables Line Infantry and Mounted Infantry to be trained and upgraded at Royal Embassies; Line Infantry train limit +8 and cost 1 population; Mounted Infantry train limit +6 and cost 1 population; Disables House of Hanover, House of Oldenburg, House of Wettin, and House of Wittelsbach
Effect & research conditions
The choice adds 8 to the Line Infantry train limit and 6 to the Mounted Infantry train limit; both unit lines cost 1 population. Research takes 5 seconds at a Royal Embassy. Selecting House of Habsburg disables House of Hanover, House of Oldenburg, House of Wettin and House of Wittelsbach, so these palace choices cannot be combined.
Research condition
Available to Germans from the Exploration Age. Research it at Royal Embassy.
When to research
Choose it when the expanded Line Infantry or Mounted Infantry roster matches the army you intend to field. The larger train limits support a broader mass, while the one-population cost changes how much army fits under the population cap. Compare the benefits with the other German House options before committing; the five-second switch is short, but it closes the listed alternatives.
A mutually exclusive House selection
House of Habsburg is one of the German House choices. Taking it disables House of Hanover, House of Oldenburg, House of Wettin and House of Wittelsbach. Decide based on the force and support you need later in the match, rather than treating all House technologies as cumulative bonuses.
Population and production planning
Line Infantry receive a train-limit increase of 8 and Mounted Infantry an increase of 6; each costs one population under this choice. This can make the available army space go further, but population is still shared with every other unit. Keep production queues and the current population cap in mind before committing resources to a large batch.
