Brest (Belarusian: Брэст Brest or traditionally Берасце, Bierascie; Lithuanian: Brestas, earlier name Lietuvos Brasta (literally, 'Lithuanian Ford'); Polish: Brześć; Russian: Брест Brest), formerly also Brest-on-the-Bug ("Brześć nad Bugiem" in Polish) and Brest-Litovsk ("Brześć Litewski" in Polish, literally "Lithuanian Brest"), is a city (population 310,800 in 2010) in Belarus at the border with Poland opposite the city of Terespol, where the Bug River and Mukhavets rivers meet. It is the capital city of the Brest voblast.
During the period of the union of the Polish–Lithuanian Commonwealth and Sweden under king Sigismund III Vasa (Polish–Swedish union), diets were held there. In 1657, and again in 1706, the town and castle were captured by the Swedes during their invasions of Polish-Lithuanian Commonwealth; on January 13, 1660 the invading Muscovite Russian army under Ivan Andreyevich Khovansky took the Brest castle in a surprise early morning attack, the town having been captured earlier, and massacred the 1700 defenders and their families (according to captain Rosestein, Austrian observer); on July 23, 1792 a battle was fought between the regiments of Duchy of Lithuania (part of Polish Army) defending the town and the invading Russian Imperial Army; on September 19, 1794 the area between Brest and Terespol was the scene of a victorious battle won by the invading Russian Imperial army under Suvorov over the Kościuszko Uprising army division under general Karol Sierakowski known in Russian sources as (Battle of Brest). Brest was annexed by Russia when the Poland-Lithuania Commonwealth was partitioned for the third time in 1795.

John II Casimir (Polish: Jan II Kazimierz Waza; German: Johann II. Kasimir Wasa; Lithuanian: Jonas Kazimieras Vaza (22 March 1609 – 16 December 1672) was King of Poland and Grand Duke of Lithuania[1] during the era of the Polish–Lithuanian Commonwealth, Duke of Opole in Upper Silesia, and titular King of Sweden 1648–1660. In Poland, he is known and commonly referred as Jan Kazimierz. His parents were Sigismund III Vasa (1566–1632) and Constance of Austria (1588–1631). His older brother, and predecessor on the throne, was Władysław IV Vasa. Related to the Habsburg rulers of the Holy Roman Empire he was the third and last monarch on the Polish throne from the House of Vasa. He was the last ruler of Polish–Lithuanian Commonwealth bearing a blood connection to the Jagiellon dynasty, through the female line.
In 1648 John Casimir was elected to succeed his half-brother on the Polish throne. The reign of the last of the Vasas in the Polish–Lithuanian Commonwealth would be dominated by the Russo-Polish War (1654–1667), followed by the war with Sweden ("The Deluge"), the scene for which had been set by the Commonwealth's two previous Vasa kings. Most of Poland was invaded by the Swedish army during the Deluge without much of a fight, due to the conspiratorial complicity of Polish and Lithuanian governors and nobility. In the course of a few years, the Commonwealth rose to force the Swedes out of Poland, ending the short-lived intrusions and campaigns.
In 1660 John II Casimir was forced to renounce his claim to the Swedish throne and acknowledge Swedish sovereignty over Livonia and the city of Riga.
On 16 September 1668, John II Casimir abdicated the Polish–Lithuanian throne, and returned to France, where he joined the Jesuits and became abbot of Abbey of Saint-Germain-des-Prés in Paris. He died in 1672.
