The Commonwealth of Poland

Social and political structure

The dual Polish-Lithuanian state, Respublica, or “Commonwealth” (Polish: Rzeczpospolita), was one of the largest states in Europe. While Poland in the mid-16th century occupied an area of about 100,000 square miles (260,000 square km), with some 3.5 million inhabitants, the Commonwealth at its largest point in the early 17th century comprised nearly 400,000 square miles and some 11 million inhabitants. As such, it was a multiethnic country inhabited by Poles, Lithuanians, Ruthenians, Germans, Jews, and small numbers of Tatars, Armenians, and Scots. It was also a multifaith country, with Roman Catholics, Protestants, Eastern Orthodox, Jews, and Muslims living within its boundaries. Certain communities lived under their own laws; the Jews, for example, enjoyed self-administration through the Council of the Four Lands.

The term Poland was used for both the entire state and the strictly Polish part of it (though the latter was officially called the Crown). This could be confusing. A supranational term like “British” was missing. The Commonwealth gradually came to be dominated by the szlachta, which regarded the state as an embodiment of its rights and privileges. Ranging from the poorest landless yeomen to the great magnates, the szlachta insisted on the equality of all its members. As a political nation it was more numerous (8–10 percent) than the electorate of most European states even in the early 19th century.

Throughout most of Europe the medieval system of estates evolved into absolutism, but in the Commonwealth it led to a szlachta democracy inspired by the ideals of ancient Rome, to which parallels were constantly drawn. The szlachta came to see in its state a perfect constitutional model, a granary for Europe, and a bulwark against eastern barbarism. Its inherent weaknesses in finance, administration, and the military were ignored.

The end of the Jagiellonian dynasty meant the beginning of unrestricted election to the throne. The first king elected viritim (i.e., by direct vote of the szlachta) was Henry of Valois, the brother of the king of France. On his accession to the throne (reigned 1573–74), which he quickly abandoned to become Henry III of France, he accepted the so-called Henrician Articles and Pacta Conventa. Presented henceforth to every new king as a contract with the noble nation, the former document provided for free election (but not during the reigning monarch’s lifetime), religious peace, biennial meetings of the Sejm (with a standing body of senators active in the interval), and the right to renounce the allegiance to the king should he break the contract.

Stephen Báthory

In 1576 the prince of Transylvania, Stephen Báthory (Stefan Batory), became king. A brilliant soldier, he closely cooperated with Jan Zamoyski, chancellor of the Crown and grand hetman (commander in chief). The most spectacular achievement of Báthory’s reign was a series of military victories (1579–81) over Ivan the Terrible of Russia. Yet it is likely that the king’s eastern policies were inspired by the ultimate goal of liberation of Hungary, which was not necessarily a Polish concern.

Sigismund III Vasa

The long reign of his successor, Sigismund III Vasa (1587–1632), raised hopes of a union with Sweden that would strengthen Poland’s standing in the north. Sigismund was the grandson of the legendary Swedish ruler Gustav I Vasa, but, as an ardent Roman Catholic and champion of the Counter-Reformation, he was unable to hold on to the crown of Lutheran Sweden, and a 10-year succession struggle ensued. His attempts to secure the throne involved Poland in a series of wars with Sweden. Although one of Lithuania’s great military commanders, Jan Karol Chodkiewicz, triumphed at Kirchholm (1605), and the Gdańsk-based navy defeated the Swedish fleet near Oliwa (1627), the truce that followed was inconclusive. The same was true for most settlements in foreign and domestic affairs.

Although Poland remained neutral in the Thirty Years’ War (1618–48), Sigismund stealthily supported the Habsburgs, a policy that contributed to a war with Turkey. Poland suffered a major defeat at Cecorą in 1620 but was victorious at Chocim (now in Khotyn, Ukraine) and negotiated peace a year later. The victory at Chocim was memorialized by poet Wacław Potocki a half century later.

There was, however, no real peace with Muscovy, then going through its Time of Troubles. The support extended by some Polish magnates to the False Dmitry (who claimed to be the son of Ivan the Terrible) eventually embroiled Poland in hostilities. The victory at Klushino in 1610 by Hetman Stanisław Zółkiewski resulted in a Polish occupation of Moscow and the election by Moscow’s boyars of Sigismund’s son Władysław as tsar. Sigismund’s veto wasted this opportunity and instead left a residue of Russian hatred of Poland.

Suspicions that Sigismund’s policies were guided by his dynastic interests contributed to a domestic confrontation: the 1606–08 rokosz (“rebellion”). Accusing the king of absolutist designs, the rokosz brought together sincere reformers (who demanded the “execution” of the laws), Roman Catholics, and Protestants, as well as magnates pursuing their own ends. Although the royal forces triumphed in battle, both the king and the reformers were losers in the political realm to the magnates posing as defenders of freedom.

Władysław IV

Władysław IV Vasa (reigned 1632–48) continued his father’s policy of strengthening the monarchy and of insisting on the rights to the Swedish throne. Some of the bellicose plans he formulated to increase his power were thwarted by the Sejm and by international circumstances. The anti-Turkish crusade he planned, however, in which Cossacks were to play a major role, contributed to the upheaval that shook the Commonwealth between 1648 and 1660—the uprising in Ukraine and war in the northeast.

Transferred as a result of the Union of Lublin from the grand duchy of Lithuania to the more ethnically homogeneous Crown, Ukraine was “colonized” by both Polish and Ukrainian great nobles. Most of the latter gradually abandoned Orthodoxy to become Roman Catholic and Polish. These “little kings” of Ukraine controlled hundreds of thousands of “subjects” and commanded armies larger than those of the regular Crown troops. In 1596 the Union of Brest-Litovsk subordinated the Eastern Orthodox church of the Commonwealth to the papacy by creating the Eastern rite (Uniate) church.

Politically, this was intended to cement the cohesion of the state vis-à-vis Moscow; instead it led to internal divisions among the Orthodox. The new Eastern rite church became a hierarchy without followers, while the forbidden Eastern Orthodox church was driven underground. Władysław’s recognition of the latter’s existence in 1632 may have come too late. The Orthodox masses—deprived of their native protectors, who had become Polonized and Catholic—turned to the Cossacks.
