Runeberg's main works included the idealist poem "" (Elk Hunters, 1832) and the epic (King Fjalar, 1844). The heroic poem (The Tales of Ensign Stål, in Finnish) written between 1848 and 1860 is considered the greatest Finnish epic poem outside the native Kalevala tradition and contains tales of the Finnish War of 1808–09 with Russia. In the war, Sweden ignominiously lost Finland, which became a Grand Duchy in the Russian Empire. The epic, which is composed episodically, emphasizes the common humanity of all sides in the conflict, while principally lauding the heroism of the Finns. The first poem ("Our Land", "Maamme" in Finnish) became the Finnish National Anthem.
