After Ottokar was killed in the 1278 Battle on the Marchfeld, Nicholas had to ward off against claims raised by his stepmother Kunigunda of Halych and her lover Záviš of Falkenstein residing at Hradec Castle near Opava.

Upon the extinction of the royal branch of the Přemyslid dynasty and the subsequent turmoil around the Bohemian throne, Henry of Carinthia gave Opava in pawn to the Silesian duke Bolesław III the Generous.

In 1377, Duke John I again separated Opava from the duchies of Racibórz and Krnov (Jägerndorf, Krnów) and granted it to his younger brothers Nicholas III (†1394), Wenceslaus I (†1381) and Przemko (†1433).

Meanwhile, in 1521, with the death of Duke Valentin of Racibórz, the Opava line of the Přemyslids had finally become extinct and all their possessions had fallen back to the Bohemian Crown, which in 1526 passed to the Habsburg monarchy.

The Austrian Duchy of Troppau ceased to exist when the Austro-Hungarian Empire was dissolved in 1918 and the area (Troppauer Land) including the city became part of Czechoslovakia.

The Prussian share (reduced by the territory of the Hlučín Region which new Czechoslovak state also reclaimed for itself) remained a part of the Silesian province until 1945, when it fell to Poland in accord with the Potsdam Agreement.
