Koniecpolski Estates
Koniecpolski Estates is a Fortress Age Polish economic technology in The Baltic Powers. It increases Villager Coin gathering from mines, Estates and Mountain Monasteries by 5%, and improves the Sejm’s automatic Coin gathering by 20%.

Effect & research conditions
Research costs 200 Food and 200 Wood and takes 40 seconds. Poles research it at the Sejm; the Cossack Hetmanate revolution instead uses the Rada. The improvement applies to the listed Villager gathering sources and the Sejm’s financial-policy income, rather than increasing all resource gathering. Further research branches into Potocki Estates for other Polish paths or Vyshnevetsky Estates for the Cossack Hetmanate.
Research condition
Poles, Fortress Age; research at Sejm, or Rada for the Cossack Hetmanate revolution
When to research
It pays off most when Villagers are already collecting Coin from the listed sources or when the Sejm is actively generating Coin. Research before a long gathering period so the bonus has time to return its 200 Food and 200 Wood cost. If the economy is short on Coin workers or needs immediate military spending, wait until the affected income stream is established.
Two income effects with different sources
The 5% bonus improves Villager work at mines, Estates and Mountain Monasteries. Separately, the Sejm’s automatic Coin work rate rises by 20%. The latter affects the Sejm’s Financial Policy income and should not be mistaken for a 20% bonus to every Villager. The strongest return comes from using both the manual gathering sources and the building income over time.
Continue along the matching estate branch
Koniecpolski Estates is the first step in an upgrade chain. Potocki Estates is the listed follow-up for the standard Polish route, while the Cossack Hetmanate uses Vyshnevetsky Estates. Choose the path that matches the revolution and building available; do not assume both branches can be researched from the same structure. Keeping the chain clear helps distinguish these related technologies and their later investments.
