Unlike some parts of Isabela like Santiago City, Echague and Alicia the history of the municipality of Quezon is relatively recent. The former municipalities have long been seats of rich and colorful historical events that influenced the lives of the people of Isabela since its creation on May 1, 1856 through a Royal Decree issued in honor of Queen Isabella II of Spain (reigned 1843 to 1868). It was in these very places where decisions that ultimately governed the lives of the local people were made by Spanish authorities.
