In the above linked post, I did not do full justice to the works of Poul Anderson. First, I should have pointed out that the three works cited are installments of a single future history. Secondly, I should also have cited a longer list of installments. The theme is novels about living in troubled times -
Mirkheim: social change on Hermes and civil war in the Polesotechnic League;
The People Of The Wind: mobilization of a planetary population for war;
The Rebel Worlds: the McCormac Rebellion on Aeneas;
The Day Of Their Return: anti-Imperial Messianism on Aeneas;
A Knight Of Ghosts And Shadows: near insurrection on Dennitza;
The Game Of Empire: popular support for an Admiral who defeats a Merseian attack, then declares himself Emperor.
Two works set in different periods before Flandry's life-time;
two centrally involving Flandry;
one not directly involving Flandry but set during his life-time;
one centrally involving Flandry's daughter, with appearances by him.
A comprehensive future history.
