History

Background

There were long discussions before signing the union treaty. Lithuanian

s were afraid of losing much of their power, since the union would make their legal status equal to that of the much more numerous Polish lower nobility. Lithuania had been increasingly on the losing side of the Muscovite–Lithuanian Wars, however, and by the second half of the 16th century, it faced the threat of total defeat in the

Livonian War The Livonian War (1558–1583) concerned control of Terra Mariana, Old Livonia (in the territory of present-day Estonia and Latvia). The Tsardom of Russia faced a varying coalition of the Denmark–Norway, Dano-Norwegian Realm, the Kingdom ...

The Polish and Lithuanian elites strengthened personal bonds and had opportunities to plan their united futures during increased military cooperation.Norman Davies, ''God's Playground: A History of Poland in Two Volumes'', Oxford University Press, p.151 Sigismund II Augustus,

Two Podlasian officers were deprived of their lands and offices. A clear motivation for Sigismund was that he was the last Jagiello and had no children or brothers who could inherit the throne. Therefore, the Union was an attempt to preserve the continuity of his dynasty's work since the personal (but not constitutional) union of Poland and Lithuania as a result of the marriage of Jadwiga and Jogaila. The Union was one of the constitutional changes required to establish a formal

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''.
