Overview
The longest-surviving Piast duchy. Centered on Płock and later Warsaw, it remained a distinct principality under a Piast line long after the rest of Poland reunified, holding fief status under the Crown. As the ducal line died out, its lands were progressively incorporated; the final incorporation came in 1526 when the last dukes died (allegedly poisoned), and Warsaw passed to the Crown — later to become Poland's capital.
