Old University of Leuven in the context of "Jansenism"

Johan van Oldenbarnevelt (Dutch pronunciation: [ˈjoːɦɑɱ vɑn ɔldə(m)ˈbɑrnəvɛlt]; 14 September 1547 – 13 May 1619), Heer van Berkel en Rodenrijs (1600), Gunterstein (1611) and Bakkum (1613), was a Dutch statesman and revolutionary who played an important role in the Dutch struggle for independence from Spain.

Van Oldenbarnevelt was born in Amersfoort. He studied law at the universities of Leuven, Bourges, Heidelberg, and Padua, and traveled in France and Italy before settling permanently in The Hague. He favored William the Silent in his revolt against Philip II of Spain, and fought in William's army. In his later years he was a supporter of the Arminians during the religious-political controversy which split the young Dutch Republic. He was the founder of the Dutch East India Company.

Pope Adrian VI (Latin: Hadrianus VI; Italian: Adriano VI; German: Hadrian VI.; Dutch: Adrianus/Adriaan VI), born Adriaan Florensz Boeyens (2 March 1459 – 14 September 1523), was head of the Catholic Church and ruler of the Papal States from 9 January 1522 until his death on 14 September 1523. The only Dutchman to become pope, he was the last non-Italian pope until the Polish John Paul II 455 years later.

Born in the Episcopal principality of Utrecht of the Holy Roman Empire of the German Nation, Adrian studied at the University of Leuven in the Low Countries, where he rose to the position of professor of theology, also serving as its rector (the equivalent of president or vice-chancellor). In 1507, he became the tutor of the future Charles V, Holy Roman Emperor, who later trusted him as both his emissary and his regent. In 1516, Charles, now King of Castile and Aragon, appointed Adrian bishop of Tortosa, Spain, and soon thereafter Grand Inquisitor of the kingdoms of Aragon and Castile. Pope Leo X made him a cardinal in 1517 and after Leo's death he was elected pope in 1522 as a compromise candidate.
