Hans Nielsen Hauge was a prominent Norwegian Lutheran lay preacher and author who lived from 1771 to 1824. He sparked a significant Pietist revival known as the Haugean movement, which emphasized personal faith and practical Christian living. Throughout his life, he traveled extensively across Norway to spread his message, resulting in fourteen separate imprisonments for preaching without official authorization. Beyond his religious work, he was a prolific writer who published thirty-three books and played a vital role in the country's early industrial development.
