Space Viking is a science fiction novel written by H. Beam Piper, originally published in 1962.
Space Viking is set in Piper’s Terro-Human future history. It tells the story of one man's search for his wife's murderer and its unexpected consequences.
A galactic war has left the Terran Federation in ruins. Formerly civilized planets have decivilized into barbarism.
Ten thousand refugees from the losing side of The Big War (The System States War of The Cosmic Computer) fled far beyond the boundaries of the Terran Federation and colonized the planet Excalibur. By the beginning of Space Viking, they had expanded to a handful of Sword Worlds (so-called because they are named after legendary swords) and had grown to a total population of three and a half billion, organized in a feudal system of kingdoms, duchies, and other small states, ruled by frequently warring noblemen. Despite their isolation and the political instability, the inhabitants managed to retain a high level of technology, including space flight.
One day, a starship rediscovered the Old Federation…
The story was originally serialized in Analog magazine (November 1962 – February 1963), then published by Ace Books in 1963.
