Here is a brief overview of the key facts and context around the 100 year void in One Piece:

This missing chunk of history remains one of the great mysteries in the overarching lore of One Piece. Fans widely theorize that understanding what transpired during the 100 year gap will reveal pivotal secrets and context about the One Piece world, its origins, and the Will of D.

Clues About When the 100 Year Void Occurred

While an exact timeframe for when the 100 year void took place has not been definitively stated, we can analyze some key clues from the story timeline to determine a reasonable estimate:

Clue #1 – Great Kingdom Fall

It is known that the Great Kingdom fell around 800-900 years ago within the One Piece timeline, marking the shift to the World Government system. This pivotal event occurred after the conclusion of the 100 year void. So the blank century must have occurred in the preceding centuries.

Clue #2 – Void Century Erasure

The void century was eliminated from history by the World Government’s ancestors about 800-900 years ago. This places the actual 100 year gap even earlier than when the Great Kingdom fell, likely in the several hundreds of years beforehand.

Clue #3 – Upper Limit of Ancient Weapon Use

Ancient weapons like Poseidon were used during the 100 year void era. Based on technological advancement timelines, these weapons were likely created no earlier than a few hundred years before the void century itself. This sets the upper limit for when the 100 year gap could have started to around 500-600 years before the Great Kingdom’s fall.

Clue #4 – World Government Ancestor Activity

The World Government’s precursor group was active during the 100 year void, leading up to their formal establishment after taking down the Great Kingdom. For them to have been established as an authority, their activity must have originated a decent period beforehand, pushing the void century even further back in the timeline.

Putting the Clues Together

Synthesizing these clues, the most likely timeframe for the 100 year void based on currently available information is approximately 500-700 years before the Great Kingdom fell 800-900 years ago.

This would place the 100 year gap around 1300-1500 years ago within the internal chronology of the One Piece world. By the modern storyline timeframe of Luffy’s adventure, the 100 year void occurred approximately 500-700 years prior.

Theorized Timeline of Key One Piece Eras

Based on the above analysis, here is a theorized timeline of when the major eras within the known One Piece timeline occurred:

Era Years Ago Within Story
Modern Storyline (Luffy’s Adventure) 0 years ago
Great Kingdom Falls 800-900 years ago
100 Year Void 1300-1500 years ago
Ancient Kingdom Era 1600+ years ago


Though the exact details are still shrouded in mystery, analyzing the current clues indicates that the crucial 100 year gap in One Piece’s history known as the void century likely occurred around 1300-1500 years prior to the modern story timeline.

This missing century over 500 years before the Great Kingdom fell is shaping up to be a pivotal period that defined the course of the entire One Piece world. The blank slate of the void century represents infinite possibilities for Oda to fill in shocking revelations and long-hidden secrets as the story progresses into its final saga. When the truth of the 100 year void is finally uncovered, it is sure to shake the foundations of everything known about One Piece thus far.
