Overview
The Dune record documents an interstellar society shaped by control of resources, environmental limits, and political authority. At its centre is Arrakis, the desert world that produces spice, the substance that enables space travel and underpins the entire Imperium. Control of this planet determines economic stability, military strength, and the balance of power between noble houses, the Emperor, and key institutions. The timeline uses AG years as its reference, reflecting a shared system recognised across worlds and administrations. Each entry marks a moment when decisions about governance, territory, or ecology produce visible consequences that ripple through the wider system.
Read in sequence, these events show how control of Arrakis repeatedly shifts and how each transition forces new responses. The transfer of authority in 10191 AG triggers a chain of conflict and consolidation that reshapes leadership and policy. In the years that follow, governance becomes increasingly complex, with competing interests attempting to stabilise or exploit the system. By the early 10200s, the effects of earlier decisions are fully visible, leading to further restructuring and long term consequences. Later entries move beyond immediate political cycles and into extended periods of rule and transformation, where ecological and social systems are deliberately altered over centuries.
The far future entries reflect a breaking point in the established order, where control can no longer be maintained in a single system. The resulting dispersal marks a shift from centralised authority to widespread expansion, redefining what the Imperium represents. This hub presents these developments as a continuous historical record, focusing on dates, locations, and outcomes rather than internal motivations.

What is the Dune timeline order?
The timeline follows AG years, beginning with 10175 AG and progressing through major events such as 10191 AG, 10202 AG, 10219 AG, 10221 AG, 13725 AG, and approximately 15200 AG. These mark key transitions in control, governance, and expansion.
Why are Dune events measured in AG years?
AG years provide a unified system across the Imperium. They are used by institutions, governments, and records to track events consistently across multiple planets.
