Biography
Niesiecki was born in Greater Poland to a burgher family. In 1699, he began training as a Jesuit in Kraków. From 1701 to 1704, he studied philosophy in Lublin, earning a master's degree. In 1707 Niesiecki started his studies in theology at the Jagiellonian University, graduating in 1711. He undertook further study in Lutsk, Krosno, Bydgoszcz, Chojnice and Kalisz.
Between 1715 and 1723, Niesiecki worked as a preacher in Masovia, Greater Poland, Lesser Poland, and Ruthenia. He taught rhetoric in Bydgoszcz and Chojnice, and ethics and mathematics in Kalisz. From 1724, he lived in the monastery of Krasnystaw, where he engaged in his life's work, compiling the Herbarz Polski (Polish Armorial or Polish Heraldic Register). Niesiecki died there on 9 July 1744.
The first volume of Herbarz Polski was published in 1728 in Lwów. Although Niesiecki initially intended to write the work in Latin, his patron, the Polish noblewoman Marianna of Potocki-Tarłowa, insisted that it appear in Polish. His commitment to avoiding unverified sources and legendary material provoked resistance from some members of the szlachta (Polish nobility). Despite this opposition, he continued the project, though the controversy contributed to delays in printing subsequent volumes. After the publication of the fourth volume, attacks from the nobility intensified, and they sent letters of protest to his Polish and German publishers. Work on the fifth volume was halted by Niesiecki's death; it was completed by Stanisław Czapliński but never published. Historians consider Niesiecki's Herbarz to meet all internationally recognised standards of genealogical scholarship.
In the 19th century, the armorial was expanded by several authors and published by Jan Nepomucen de Bobrowicz in Leipzig.
