Fontane was a well-known poet and famous for his travel writings in Wanderungen durch die Mark Brandenburg, and had been a full-time writer from the age of 30. Later in life he turned to writing novels of which Before the Storm was the first, published when he was 58. Fontane described the general subject of the novel as "the entry of a great idea, of a great moment into an essentially very simple class and condition of men". He wrote that he wanted to capture "the great emotion" among Prussians fighting back against Napoleon and simultaneously "not to be too disturbing, or even particularly gripping".
