Historical Record
By the middle decades of the 22nd century, Earth falls under one of the bleakest occupations in Doctor Who history. This site uses 2157 as the approximate anchor date, but the source itself presents the conflict as a broader 22nd century event. London stands in ruins, public life has collapsed, and Dalek patrols dominate the landscape. The scale of the takeover is visible in empty streets, damaged infrastructure, and the near absence of normal civilian authority. Human survivors live in fear, evade detection where possible, and cling to fragmented resistance networks. This is not a brief raid or attempted invasion. It is a sustained conquest in which the Daleks hold territory and impose their will directly on Earth.
The occupation depends on both machinery and terror. Human beings are reduced to labour, prisoners, or fugitives. Dalek saucers and ground forces operate with confidence because they believe the planet is already broken beyond recovery. Yet organised resistance still exists. Groups of survivors continue to fight from the margins, attempting sabotage and preserving a sense of purpose under impossible conditions. When the Doctor, Susan Foreman, Ian Chesterton, and Barbara Wright arrive, they encounter not a single battlefield but a whole world warped by occupation. The ruined cityscape around them gives the conflict a heavy historical weight. Earth is no longer merely threatened by the Daleks. It has already been taken.
The Daleks' wider plan makes the crisis even more severe. They are not content simply to rule the planet. They intend to exploit Earth on an immense physical scale by mining out the planet's core and using the world as part of a larger interplanetary design. That objective turns occupation into engineering catastrophe. The damage is not only social or political. It is geological and existential. Humanity is resisting an enemy willing to destroy the conditions of life itself in pursuit of mobility and power. In this environment, every successful act of resistance matters, because the stakes are not local freedom alone. The stakes are the continued existence of Earth as a stable home.
This future event also matters for personal historical reasons. It marks Susan Foreman's departure from the Doctor's travels and closes one of the earliest chapters of the series. But even without that personal change, the occupation would remain one of the essential future anchors of Doctor Who chronology. It provides one of the clearest early images of Earth after complete defeat, and one of the clearest statements that resistance remains possible even then. As a timeline entry, the Dalek invasion of Earth defines the 22nd century as an era in which humanity's survival depends on endurance, local courage, and the refusal to accept Dalek control as final.

FAQ
Q: When does the Dalek invasion of Earth take place in Doctor Who?
The serial places it in the 22nd century rather than giving one uncontested exact calendar date. This page uses 2157 because that is the anchor supplied in your event list, while the underlying canon remains broader.
Q: What makes this invasion important?
It shows Earth not at the edge of defeat but already deep inside occupation. That makes it one of the earliest and strongest examples of future history in Doctor Who, with London ruined, resistance active, and the Daleks trying to use the planet for a much larger purpose.
