Hungary and Bohemia. Additionally, Mikolaj "the Black" was the deputy to the Grand Prince when the latter was abroad. From that time on, the Radziwiłłs were also granted the privilege of keeping legal acts and other state documents in Nesvizh. In 1583 bishop Jerzy Radziwiłł was elevated to the cardinalate by Pope Gregory XIII, established a closer relationship with the influential noble banking families Altoviti and Strozzi. Later prince Aleksander Ludwik Radziwiłł married Lucrezia Maria Strozzi, great-granddaughter of Bindo Altoviti and Filippo Strozzi. During this time until the first half of the 17th century, the Radziwiłłs were the most influential and richest family among the magnate dynasties of the Grand Duchy of Lithuania. This status enabled them, along with very few other families, to have their own army. In 1528, the Radziwiłłs owned 18,240 houses, thus being able to have cavalry of 760 horsemen. In 1567, 28,170 houses provided for an expanded 939 horsemen and 1586 infantrymen. In the 18th century, the army of Hieronim Florian, for instance, had 6,000 men and was equal to the entire armed forces of the Grand Duchy of Lithuania. Members of the Radziwiłł family held important state posts in the Rzeczpospolita and in the Grand Duchy of Lithuania. 8 chancellors, 7 hetmans, 15 castellans, 19 marszałeks, and 19 voivodes, almost exclusively representing the Grand Duchy of Lithuania, rather than the Crown, belonged to the dynasty. Radziwiłłs were members of the parliament and of the Tribunal of the Grand Duchy of Lithuania. They also held high military posts and took part in the Livonian War, Russo-Polish War of 1647–1667, Northern Wars, participated in the Napoleonic campaign, and the Kościuszko Uprising.

Such conjugal unions continued in the 17th and 18th centuries. Karol Stanisław Radziwiłł (1734–1790) of the Nieśwież line was the wealthiest magnate in Poland, in the second half of the 18th century, and one of the richest men in Europe. As a patriot, he fought for a free nation that soon after his death would be partitioned between Austria, Prussia and the Russian Empire. During the Great Sejm from 1788 until he died in 1790, he was a leading opponent of reform and King Stanisław II Augustus and his allies, the members of the so-called Familia political party
