Lady Inger of Ostrat

Lady Inger of Ostrat (original title: Fru Inger til Østeraad) is a play by Henrik Ibsen, inspired by the life of Inger, Lady of Austraat. The play, the third work of the Norwegian's career, reflects the birth of Romantic Nationalism in the Norway of that period, and had a strongly anti-Danish sentiment. It centers on the Scandinavia of 1510–1540 as the Kalmar Union collapsed, the impacts of the Reformation were becoming evident in Norway, and a last desperate struggle was being mounted to maintain Norwegian independence. Its initial sentiments were so strongly anti-Danish that Ibsen ultimately toned them down.

Norwegian literature was virtually nonexistent during the period of the Scandinavian Union and the subsequent Dano-Norwegian union (1387—1814) — Ibsen characterized that period as "Four Hundred Years of Darkness." Ibsen was a major participant in a flood of nationalistic romanticism that followed the "Four Hundred Years of Darkness" and is recognized as one the great four contributors of this period (the others being Bjørnstjerne Bjørnson, Alexander Kielland, and Jonas Lie). A unity of purpose pervades the whole period, recreation of a national culture based on the almost forgotten past. Subsequent research has shown the play Fru Inger til Østeraad deviates rather liberally from the actual historical events, and should be understood in its context as a statement of nationalism.

The first production in the UK since 1947 took place at the Barons Court Theatre in 2013.
