Pierre-René Rogue was a French Catholic priest of the Congregation of the Mission who lived in Vannes during the late 18th century. Known for his deep faith and short stature, he earned the nickname "the wee priest" from the local community. During the French Revolution, he refused to swear the oath of allegiance required by the new government, choosing instead to remain loyal to the Church. This decision eventually led to his arrest and execution in 1796, making him a martyr for his convictions.
