Le Petit Vingtième (French: [lə pti vɛ̃tjɛm], The Little Twentieth) was the weekly youth supplement to the Belgian newspaper Le Vingtième Siècle ("The Twentieth Century") from 1928 to 1940. The comics series The Adventures of Tintin first appeared in its pages.
Le Vingtième Siècle was a Catholic and conservative newspaper published in Brussels, led by abbot Norbert Wallez. In 1925, 18-year-old Hergé (Georges Prosper Remi), the creator of Tintin, worked there, first as a clerk and, after he fulfilled his military service, as an illustrator for the main pages and for some supplements like the weekly arts pages and the women's section.
In 1928, the abbot decided to start a weekly 8-page youth supplement, appearing every Thursday. He called it Le Petit Vingtième (The Little Twentieth). Hergé was named Editor-in-Chief. In the first issue, appearing on November 1, 1928, he illustrated a short comic made by Desmedt, the sports editor of the newspaper called Les Aventures de Flup, Nénesse, Poussette et Cochonnet. Sensing that this comic lacked spirit and was rather old-fashioned compared to the current American comics and to the works of Alain Saint-Ogan, Hergé started working on his own comic. In 1927, he met Germaine Kieckens, the secretary of the abbot at the newspaper. They were engaged in 1932 and married on July 20 of the same year.
