Launched in 1908 as an all-fiction offshoot of the general-interest magazine, The Scrap Book (1906-1911), The Cavalier ran for just 163 issues but nevertheless played a significant part the development of the pulp magazine industry. Originally published on fine book paper with refined, 'classy' covers, the Munsey company changed its format to pulp paper in 1909, and from 1911 onwards included in-text illustrations. The magazine also traded in its sophisticated covers for more exciting, colorful images of adventure.
In January 1912, The Cavalier absorbed its predecessor, The Scrap Book, and became the first weekly pulp. It also temporarily adopted the name The Cavalier and The Scrap Book. Although the magazine effectively folded in May 1914 when Munsey's merged it with The All-Story, the new venture was known for aaabout a year as All-Story Cavalier Weekly.
