Cultural in the east (orange color) After the Union, the Lithuanian nobles had the same formal rights as the Polish to rule the lands and subjects under their control. However, political advancement in the
Catholic-dominated Commonwealth was a different matter. By the late 15th century, the
Polish language was already making rapid inroads among the Lithuanian and Rus' elites. thus considering the Union (along with the
Kalmar Union, the several
Acts of Union in the British Isles and other similar treaties) to be a predecessor of the
Maastricht Treaty. The former, however, created a state of countries more deeply linked than the present-day European Union.
Economic The union brought about the Polish
colonization of Ruthenian lands and increasing enserfment of Ruthenian peasantry by the szlachta. Although the conditions for peasants in the Commonwealth was quite dire, compared to the West (see
second serfdom), the peasants in the Commonwealth had more freedom than those in
Russia; hence peasants (as well as to a lesser extent nobility and merchants) escaping from Russia to the Commonwealth became a major concern for the Russian government, and was one of the
factors ultimately leading to the partitions of Poland. A common coin, the
złoty, was introduced.
Execution of
crown lands was not extended to the Grand Duchy.
Geographical The Union created one of the largest and most populous states in 17th-century Europe (excluding the states not completely in Europe, i.e. the
Russian and
Ottoman Empires). As part of the Union, Lithuania lost
Podlaskie,
Volhynia,
Podolia and
Kiev voivodeships to the
Crown of the Kingdom of Poland.
Legal The
Statutes of Lithuania declared the laws of the Union that conflicted with them to be unconstitutional. The First Statute of Lithuania was also used in the territories of Lithuania that were annexed by Poland shortly before the Union of Lublin (except for Podlaskie). These conflicts between statutory schemes in Lithuania and Poland persisted for many years, and the Third Statute of Lithuania remained in force in territories of the Grand Duchy of Lithuania even after partitions, until 1840. Attempts to limit the power of Lithuanian magnates (especially the
Sapieha family) and unify the laws of the Commonwealth led to the
koekwacja praw movement, culminating in the
koekwacja reforms of the
Election Sejm of 1697 (May–June), confirmed in the
General Sejm of 1698 (April) in the document
Porządek sądzenia spraw w Trybunale Wielkiego Księstwa Litewskego.
Military Poland provided military aid in the wars after the union of the two entities, which was crucial for the survival of the Grand Duchy. Nevertheless, on 29 May 1580, a separate ceremony was held in the
Vilnius Cathedral during which bishop
Merkelis Giedraitis presented
Stephen Báthory (King of Poland since 1 May 1576) a
decorated sword and a hat adorned with pearls (both were sanctified by
Pope Gregory XIII himself), while this ceremony manifested the sovereignty of the Grand Duchy of Lithuania and had the meaning of
elevation of the new Grand Duke of Lithuania, this way ignoring the stipulations of the Union of Lublin. A common parliament, the Sejm, held its sessions in
Warsaw; it had 114 deputies from the Polish lands and 48 from Lithuania. The Senate had 113 Polish and 27 Lithuanian senators. Poland and the Grand Duchy were to have a common foreign policy. ==Legacy==
