In the name of love [countryhumans] CKP x GDL

The story begins sometime in the early 12th century. The Kingdom of Poland is growing stronger, but its expansion is interrupted by district division. After bringing the Teutonic Order to Masovia and betraying it, Poland concludes a pact with Lithuania to defeat the army that was dangerously approaching their territory. Russian tsarism and the whole of Europe will get involved in all this confusion.
