1919, influenced by the events of the German Revolution of 1918–19, he published, together with poet Julian Tuwim, his first book of political illustrations: Rewolucja w Niemczech (Revolution in Germany), which was a satire on the Germans, who need the Kaiser's and the military's consent even to start a revolution. In the same year, Szyk had to take part in warfare again – during the Polish–Soviet War (1919–1920), in which he served as a Polish cavalry officer and as the artistic director of the propaganda department of the Polish army in Łódź. In France In 1921 Arthur Szyk and his family moved to Paris where they stayed until 1933. The relocation to Paris is marked by a breakthrough in the formal aspect of Szyk's works. While Szyk's prior book illustrations were drawings in pen and ink (Szyk had illustrated six books before 1925, including three published in the Yiddish language), the illustrations for the books published in Paris were full colour and full of detail. The first book illustrated in this way was the Book of Esther (Le livre d'Esther, 1925), followed by Gustave Flaubert's dialogue The Temptation of Saint Anthony (La tentation de Saint Antoine, 1926), Pierre Benoît's novel Jacob's Well (Le puits de Jacob, 1927) and other books. Those illustrations, which are characterized by a rich diversity of colours and detailed presentation, deliberately referred to the medieval and renaissance traditions of illumination of manuscripts, often with interspersed contemporary elements. Szyk drew himself as one of the characters in the Book of Esther.. The only stylistic exception is illustrations to the two volume collection of humorous anecdotes about Jews Le juif qui rit (1926/27), in which the artist returned to simple black and white graphics. (Paradoxically, the book, one of the best known of his works, met with criticism as repeating antisemitic stereotypes.) The artist's reputation was also enhanced by exhibitions which were organized by Galeries Auguste Decour (the art gallery first exhibited Szyk's works in 1922). Szyk's drawings were purchased by the Minister of Education and Fine Arts Anatole de Monzie and the New York businessman Harry Glemby. Szyk had many opportunities to travel for his art. In 1922, he spent seven weeks in Morocco, then a protectorate of France, where he drew the portrait of the pasha of Marrakech – as a goodwill ambassador he received the Ordre des Palmes Académiques from the French government for this
