Over time, Poland's nobles became increasingly reluctant to over-expand the nobility (or rather saw need to prevent it), since heraldic adoption was open to the possibility of abuse, adoption for a fee, buying nobility (especially by wealthy city burghers) and uncontrolled expansion of the nobility. This caused the disappearance of ennoblement by heraldic adoption by the end of the 16th century, and also limited ennoblement in favour of the King by requiring parliamentary consent from Poland's general sejm.
