These are comparisons, not claims that every political change happened neatly on one date. Open one, then move the sliders and inspect a place you know.
Browse every available world map
Historical maps by year
Each year page names the mapped regions, reports source precision, links adjacent snapshots, and opens the explorer at that exact frame. Missing years stay missing: frames before 1886 are milestone snapshots, and from 1886 CShapes adds a frame for every year in which state borders changed.
For a guided chronology, start with 1000, 1492 , and the post-Napoleonic settlement in 1815. Track imperial and wartime shifts through 1880, 1914, 1920, 1938 , and 1945. Then compare decolonization in 1960, the post-Cold War map in 1994 , and the latest dataset frame in 2023.

Read the map honestly
A border line is a sourced interpretation
Recent frames can represent documented sovereign boundaries. Older frames may combine states, cultural regions, spheres of authority, and approximate frontiers that overlap.
What this explorer can answer
- Which mapped entity covers a coordinate in an available year.
- How two available snapshots differ side by side.
- How a point's ruler or region label changes across snapshots.
- Whether source data marks a border as approximate or more firmly determined.
What it cannot prove by itself
It cannot settle a disputed sovereignty claim, turn fuzzy authority into a surveyed frontier, or replace primary historical research. The upstream Historical Basemaps project explicitly describes its work as in progress and recommends comparison with other sources before academic use.
Coverage, without the 'every year' myth
The explorer contains 53 Historical Basemaps snapshots through 2010 and 106 CShapes frames: one for every year from 1886 in which state borders changed, and every year from 2011 through 2023. Moving between frames shows changes in the available evidence; it does not invent missing years.

Coverage: 53 available snapshots from prehistory through 2010
CShapes 2.1 borders
Time-aligned source
Sovereign-border dataset of independent states and colonies, dated to the day. It fills every year since 1886 in which state borders changed and covers 2011 through 2023 annually. It does not code wartime occupation.
Coverage: Independent states and dependent territories, 1886–2023; each frame shows borders on 1 July

Does this map contain every historical year?
Not before 1886. It contains 53 milestone snapshots through 2010, plus CShapes frames for every year since 1886 in which state borders changed and for every year from 2011 through 2023. The timeline moves between available evidence instead of fabricating missing years.
Are ancient borders exact?
Usually not. Authority could overlap, fade across frontier zones, or follow geography that has since changed. The source includes a border-precision field, and the explorer shows that status when available.
What does point history mean?
The explorer keeps one coordinate fixed and checks which mapped polygon covers it in each snapshot. That survives place-name changes better than following one modern country label backward.
How are corrections handled?
Submissions enter a private queue with the relevant map state. Nothing is published automatically. Approved notes appear only when the contributor granted permission, and the public response records whether the issue was accepted, applied, or declined.
