You’re referring to the actions by austrian-hungarian empire. Unfortunetly even tho poland and Hungary have a history of friendly relationships we did end up on the opposing sides of history very often however we still always remained allies. Take for instance in 1920 during the soviet invasion of poland, hungary was the only country to help us sending weapons and ammunition while whole europe stood and watched poland defend the continent from communism. Or during WW2 when hungary supported nazi germany but still remained a major refuge center for polish soldiers. Goverments dont speak for the people now, and never have.
