Franciszek Kareu

Very Rev. Franciszek Kareu, S.J. (10 December 1731, Orsha – 11 August 1802, Polatsk) was a Jesuit monk, missionary and teacher in the lands of today's Belarus. He was Temporary Vicar General of the Society of Jesus in Russia from 1799 to 1801. After Pope Pius VII's official approval of the Jesuits' existence in Russia, he was declared Superior General of the Society of Jesus (1801–1802)

Born of an English family settled in Grand Duchy of Lithuania, he followed the usual course of studies, humanities and philosophy, in Orsha before joining the Jesuits. Two years of novitiate in Vilnius (1754–56) were followed by a bout of teaching at Kražiai College (1756–58) and theology studies in Pinsk (1759–63) where he was ordained priest in 1762.

After being a missionary in several places, Minsk, Nesvizh, and Slutsk, Kareu arrived in 1768 in Polatsk where he studied architecture under the guidance of Gabriel Lenkiewicz, along with teaching philosophy and mathematics at the Jesuit College in Polatsk (1769–72). Being close to Stanislaus Czerniewicz and Lenkiewicz, he helped them in their efforts to keep the Society of Jesus going in Russia. He was made the Rector of the High School of Orsha in 1782 and took part in the Regional Congregation of 1782 and 1785 that elected successively Cerniewicz and Lenkiewicz, Temporary Vicar in Russia. After 1785, Kareu was made Rector of the most prestigious Jesuit College in Russia, Polatsk. In this period, he funded the purchase of a printing press from which, school manuals, philosophical and theological treatises and devotional books were produced.
