Two important ecclesiastical entities with high degree of autonomy within the Crown of Poland were Duchy of Siewierz and Prince-Bishopric of Warmia.

Fiefs of Crown of Poland included the Lauenburg and Bütow Land and two condominiums (joint domain) with the Grand Duchy of Lithuania: Duchy of Livonia and Duchy of Courland and Semigallia.

Some enclaves in the Hungarian area of Spisz were also part of Poland (due to the Treaty of Lubowla).

The Grand Duchy of Lithuania or just colloquially Lithuania (Lithuanian: Lietuva) is the name for the territories under direct Lithuanian administration during medieval sovereign Lithuanian statehood, and later until the end of common Polish-Lithuanian Commonwealth statehood in 1795.

Just before the Union of Lublin (1569), four voivodeships (Kiev, Podlaskie, Bracław, and Wołyń) of the Grand Duchy of Lithuania were transferred to the Polish Crown by direct order of Sigismund II Augustus, and the Duchy of Livonia, acquired in 1561, became a condominium (joint domain) of both Lithuania and Poland. The Duchy of Courland and Semigallia was another condominium.

After 1569, Lithuania had eight voivodeships and one eldership remaining:

One of the oldest Lithuanian territories, the Duchy of Samogitia, had a status equal to that of a voivodeship, but retained the name Duchy.

After the Livonian War (1558–1582), Lithuania acquired vassal state Duchy of Courland with capital in Jelgava.

The Duchy of Prussia was a duchy in the eastern part of Prussia from 1525 to 1701. In 1525 during the Protestant Reformation, the Grand Master of the Teutonic Knights, Albert of Hohenzollern, secularized the Prussian State of the Teutonic Order, becoming Albert, Duke in Prussia. His duchy, which had its capital in Königsberg (Kaliningrad), was established as a fief of the Crown of Poland, as had been Teutonic Prussia since the Second Peace of Thorn in October 1466. This treaty had ended the War of the Cities or Thirteen Years' War and provided for the Order's cession of its rights over the western half of its territories to the Polish crown, which became the province of Royal Prussia, while the remaining part of the Order's land became a fief of the Kingdom of Poland (1385–1569). In the 17th century King John II Casimir of Poland submitted Frederick William to regain Prussian suzerainty in return for supporting Poland against Sweden. On 29 July 1657, they signed the Treaty of Wehlau in Wehlau (Polish: Welawa; now Znamensk), whereby Frederick William renounced a previous Swedish-Prussian alliance and John Casimir recognised Frederick William's full sovereignty over the Duchy of Prussia.[3] Full sovereignty was a necessary prerequisite for upgrading the Duchy to Kingdom of Prussia in 1701.

The Duchy of Livonia[4] was a territory of the Grand Duchy of Lithuania – and later a joint domain (Condominium) of the Polish Crown and the Grand Duchy of Lithuania

The Duchy of Courland and Semigallia is a duchy in the Baltic region that existed from 1562 to 1791 as a vassal state of the Grand Duchy of Lithuania and later the Polish–Lithuanian Commonwealth. From 1685, District of Pilten was in union with the duchy. In 1791 it gained full independence, but on 28 March 1795, it was annexed by the Russian Empire in the Third Partition of Poland. The duchy also had colonies in Tobago and Gambia

Caffa

In 1462, during the expansion of the Ottoman Empire and the Crimean Tatars, Caffa placed itself under the protection of King Casimir IV of Poland. The proposition of protection was accepted by the Polish king but when the real danger came, help for Caffa never arrived.[5]

Thought was given at various times to the creation of a Grand Duchy of Ruthenia, particularly during the 1648 Cossack insurrection against Polish rule in Ukraine. Such a Duchy, as proposed in the 1658 Treaty of Hadiach, would have been a full member of the Commonwealth, which would thereupon have become a tripartite Polish–Lithuanian–Ruthenian Commonwealth, but due to szlachta demands, Muscovite invasion, and division among the Cossacks, the plan was never implemented.

For similar reasons, plans for a Polish–Lithuanian–Muscovite Commonwealth also were never realized, although during the Polish–Muscovite War (1605–18) the Polish Prince (later, King) Władysław IV Waza was briefly elected Tsar of Muscovy.
