Lithuanian and Polish rule
By the middle of the 14th century, Ukrainian territories were under the rule of three external powers—the Golden Horde, the grand duchy of Lithuania, and the kingdom of Poland.
The steppe and Crimea, whose coastal towns and maritime trade were now in the hands of the Venetians and Genoese, formed part of the direct domains of the Tatar Golden Horde. This was the westernmost successor of Genghis Khan’s Mongol empire, whose khan resided at Sarai on the Volga River. By the mid-15th century the Golden Horde was in a process of disintegration. One of its successor states was the Crimean khanate, which after 1475 accepted the suzerainty of the sultans of the Ottoman Empire. Both the Crimean Peninsula and large areas of the adjoining steppe continued under the khanate’s rule until its annexation to the Russian Empire in 1783.
Elsewhere in Ukraine, Mongol rule was largely indirect, limited to exactions of taxes and tribute whose collection was delegated to the local princes. It was also relatively short-lived; northwestern and central Ukraine became an arena of expansion for a new power that had arisen in the 13th century, the grand duchy of Lithuania.
Having already over the course of a century incorporated all the lands of Belarus, Lithuania under Grand Duke Algirdas advanced rapidly into Ukraine. In the 1350s Chernihiv and adjacent areas—and in the 1360s the regions of Kyiv and, to its south, Pereyaslav and Podolia (Podillya)—were occupied by Lithuania. Competition with Poland over the former Galician-Volhynian principality ended in the 1380s in partition, by which Lithuania gained Volhynia and Poland was confirmed in its possession of Galicia. Thus, Lithuanian control extended over virtually all the Ukrainian lands as far as the open steppe and even, briefly, to the Black Sea.
Within the grand duchy the Ruthenian (Ukrainian and Belarusian) lands initially retained considerable autonomy. The pagan Lithuanians themselves were increasingly converting to Orthodoxy and assimilating into Ruthenian culture. The grand duchy’s administrative practices and legal system drew heavily on Slavic customs, and an official Ruthenian state language (also known as Rusyn) developed over time from the language used in Rus.
Direct Polish rule in Ukraine in the 1340s and for two centuries thereafter was limited to Galicia. There, changes in such areas as administration, law, and land tenure proceeded more rapidly than in Ukrainian territories under Lithuania. However, Lithuania itself was soon drawn into the orbit of Poland following the dynastic linkage of the two states in 1385/86 and the baptism of the Lithuanians into the Latin (Roman Catholic) church. The spread of Catholicism among the Lithuanians and the attendant diffusion of the Polish language, culture, and notions of political and social order among the Lithuanian nobility eroded the position of the Orthodox Ruthenians, as had happened earlier in Galicia. In 1569, by the Union of Lublin, the dynastic link between Poland and Lithuania was transformed into a constitutional union of the two states as the Polish-Lithuanian Commonwealth. At the same time, the greater part of the Ukrainian territories was detached from Lithuania and annexed directly to Poland. This act hastened the differentiation of Ukrainians and Belarusians (the latter of whom remained within the grand duchy) and, by eliminating the political frontier between them, promoted the closer integration of Galicia and the eastern Ukrainian lands. For the next century, virtually all ethnically Ukrainian lands experienced in common the direct impact of Polish political and cultural predominance.
Social changes
Over three centuries of Lithuanian and Polish rule, Ukraine by the middle of the 17th century had undergone substantial social evolution. The princely and boyar families tracing their roots to Kyivan Rus had largely merged and become part of the privileged noble estate of Lithuania and Poland. Long attached to the Orthodox religion and the Ruthenian language and customs, the Ruthenian nobility in the late 16th century became increasingly prone to Polonization, a process often initiated by education in Jesuit schools and conversion to Roman Catholicism.
With the growth of towns and urban trades, especially in western Ukraine, the burghers became an important social stratum. They were divided both in terms of an internal social hierarchy associated with the guild system and by religion and ethnicity. Since the 13th century many Poles, Armenians, Germans, and Jews had settled in the cities and towns, where the Ukrainians were often reduced to a minority. Although the burghers came to play an influential role within the Ukrainian community, legal disabilities imposed on non-Catholics progressively limited their participation in the municipal self-government enjoyed by many cities and towns under Magdeburg Law.
In the period of Polish rule the conditions of the peasantry steadily deteriorated. The free peasantry that had still existed into the late Lithuanian period underwent rapid enserfment, while serf obligations themselves became more onerous (see serfdom). Peasant unrest increased toward the end of the 16th century, especially in eastern Ukraine. The sparsely settled lands were opened to Polish proprietorship for the first time, and large latifundia (agricultural estates worked by a large number of peasants) were established through royal grants to meet the demands for grain on the European markets. To attract labour to the new estates, peasants were granted temporary exemptions from serf obligations; the expiration of these exemptions and the reintroduction of servitude among a population grown accustomed to freedom led to much discontent and peasant flight into the “wild fields”—the steppe lands to the east and south. Tensions were exacerbated by the fact that, while the peasants were Ukrainian and Orthodox, the landlords were largely Polish (or Polonized) and Roman Catholic, and the estate stewards or leaseholders for absentee proprietors frequently were Jewish. Thus, social discontent tended to coalesce with national and religious grievances.
Religious developments
As social conditions among the Ukrainian population in Lithuania and Poland progressively deteriorated, so did the situation of the Ruthenian church. The Roman Catholic Church, steadily expanding eastward into Ukraine, enjoyed the support of the state and legal superiority over the Orthodox. External pressures and restrictions were accompanied by a serious internal decline in the Ruthenian church. From the mid-16th century, both Catholicism, newly reinvigorated by the Counter-Reformation and the arrival of Jesuits in Poland, and Protestantism (albeit temporarily) made inroads, especially among the Ruthenian nobility.
Attempts to revive the fortunes of the Ruthenian church gathered strength in the last decades of the 16th century. About 1580 Prince Konstantyn Ostrozky founded at Ostroh in Volhynia a cultural centre that included an academy and a printing press and attracted leading scholars of the day; among its major achievements was the publication of the first complete text of the Bible in Slavonic. Lay brotherhoods, established by burghers in Lviv and other cities, maintained churches, supported schools and printing presses, and promoted charitable activities. The brotherhoods were frequently in conflict with the Orthodox hierarchy, however, on questions of authority over their institutions and clerical reforms.
Religious developments took a radical turn in 1596 when, at a synod in Brest, the Kyivan metropolitan and the majority of bishops signed an act of union with Rome. By this act the Ruthenian church recognized papal primacy but retained the Eastern rite and the Slavonic liturgical language, as well as its administrative autonomy and traditional discipline, including a married clergy.
This so-called Uniate church was unsuccessful in gaining the legal equality with the Latin church foreseen by the agreement. Nor was it able to stem the process of Polonization and Latinization of the nobility. At the same time, the Union of Brest-Litovsk caused a deep split in the Ruthenian church and society. This was reflected in a sizable polemical literature, struggles over the control of bishoprics and church properties that intensified after the restoration of an Orthodox hierarchy in 1620, and numerous acts of violence. Efforts to heal the breach in the 1620s and ’30s were ultimately fruitless. (See also Eastern Rite church.)
