Facing the Flag or For the Flag (French: Face au drapeau) is an 1896 patriotic novel by Jules Verne. The book is part of the Voyages extraordinaires series.
Like The Begum's Millions, which Verne published in 1879, it has the theme of France and the entire world threatened by a super-weapon with the threat finally overcome through the force of French patriotism.
It can be considered one of the first books dealing with problems which were to become paramount half a century after its publication in World War II and the Cold War: brilliant scientists discovering new weapons of great destructive power, whose full utilization might literally destroy the world; the competition between superpowers to obtain overwhelming stockpiles of such weapons; and, efforts of other nations to join the nuclear club.

Jules Verne (February 8, 1828- March 24, 1905) was a French writer. He was one of the first authors to write science fiction. He was born in the city of Nantes, France. His father was a lawyer, and at the beginning, Verne wanted to study law as well. When he was nineteen, he started writing long pieces of literature, but his father wanted him to earn money as a lawyer, not as a writer. In 1847, his father sent him to Paris to start studying law.
In 1848, Jules Verne, on a visit home, fell in love, but the girl's parents did not want her to marry him. Verne was depressed when he heard that the girl had been married to someone else - a rich, older man. In his stories, Jules Verne often writes about women married to people they do not love.
He returned to Paris to find it on the verge of revolution: the French Revolution of 1848 deposed the king, and Louis-Napoléon Bonaparte was elected as the first president of the Republic of France. Verne continued to study law until 1851, but all the time he was writing and meeting with other authors and artists.
Finally, in 1852, he decided to give up being a lawyer, and become a full-time professional writer instead. His father was very unhappy with this decision, but Verne was stubborn and strong-minded, so he went ahead with his plans. Verne went to Paris to try to find success. At first, he did not find any fame. Over time, he became a fan of science, while becoming well-known for his writing. His love of science and writing led him to write stories and novels that are now called "science fiction". Many people say Jules Verne was the creator of the science fiction genre.
