The Future History Timeline
Heinlein was the first modern science fiction author to construct a coherent future history: an interconnected chart mapping sociological, technical, and political epochs from the mid-20th century to the deep galactic diaspora.
The Opening Decades
The transition from the discovery of the Pinero death-predictor to atomic energy, the establishment of the early lunar colonies, and commercial spaceflight.
The Discovery of Life-Line
Dr. Hugo Pinero invents a machine that accurately predicts the exact lifespan of any human subject, shaking insurance cartels and sparking existential legal battles over predestination.
Industrial Automation and the Rolling Roads
Massive mechanized strip-roadways replace surface highways across North America. When radical technician factions strike, the fragile interdependence of modern technocracy is exposed.
Atomic Power Plant Failures
Early terrestrial nuclear breeder reactors operate under terrifying psychological stress. The constant dread of runaway chain reactions forces humanity to move hazardous atomic power off Earth into orbital stations.
The Commercial Conquest of the Moon
Financier and visionary Delos David Harriman orchestrates private capital, patent pools, and global marketing syndicates to fund the first successful manned lunar landing, securing private title to Luna.
The Interplanetary Expansion
The era of the Space Patrol, mass interplanetary migration, the emergence of lunar industry, and the first frontier colonies on Mars and Venus.
The Founding of the Space Patrol
To prevent nuclear blackmail between rival Earth powers, a supranational military order, the Interplanetary Patrol, is entrusted with atomic warheads in orbit, bound by strict personal honor.
The Great Lunar and Martian Migration
The Solar System opens to human homesteading. Rhysling wanders the spaceways composing the folk anthems of spacefarers, while frontier families establish agrarian domes on Ganymede and Mars.
Resource Exploitation and Colonial Friction
Contract labor on Venusian swampland plantations deteriorates into debt slavery. Economic self-interest between Earth finance and frontier colonists sets the stage for future colonial revolt.
The Crazy Years and The Prophet
A period of psychological hysteria on Earth gives birth to a brutal theocracy: the Prophet Nehemiah Scudder overthrows the Constitution and creates the New Jerusalem.
The Crazy Years
Overpopulation, urban collapse, rapid psychological alienation, and sensationalist mass media induce collective societal neurosis. Standard democratic norms break down across Earth.
Rise of the Theocracy
Evangelist Nehemiah Scudder allies with television networks and private militias to sweep into the White House. He suspends the Constitution, establishing a hereditary theocratic dictatorship.
The Second American Revolution
The United States underground resistance, allied with the Freemasons and armed with psychometric computers, topples the Prophet Incarnate in New Jerusalem, restoring civil liberties.
The Covenant and Social Peace
A new constitutional settlement, the Covenant, reorganizes society around personal freedom, non-aggression, and psychometrics, banishing prison in favor of exile to Coventry.
The Adoption of the Covenant
Humanity establishes a non-authoritarian legal code based on psychological harm evaluation. Citizens who refuse to abide by the Covenant are not imprisoned; they are exiled beyond the Barrier to Coventry.
Development of the Libby Drive
Math prodigy Slipstick Libby invents real-time spatial navigation calculations, paving the way for gravity-manipulating faster-than-light interstellar engines.
The Howard Families and Diaspora
The secret selective breeding program of the Howard Foundation is revealed. Humanity achieves physical longevity and begins its permanent diaspora into the deep galaxy.
The Flight of the Howard Families
Envious of the long-lived Howard Families, short-lived mortals attempt to extract their supposed secret through force. Led by Lazarus Long, 100,000 Howard descendants commandeer the starship New Frontiers into deep space.
Return and Longevity for All
The Howard Families return to Earth with Libby's perfected faster-than-light drive and alien medical techniques, granting rejuvenation therapies and centuries of healthy lifespan to all humankind.
The Tertiary Era and The World as Myth
Centuries across dozens of colonized worlds. Lazarus Long reflects on millennia of experience. The continuum craft Gay Deceiver breaches alternate dimensions, establishing the World as Myth where creators, characters, and multiverses co-exist.
