Historical borders and dated map events with source attribution and coverage limits.
Scored across 4 tools
Each tool has a distinct primary purpose: link generation, polity lookup, event search, and year-based polity listing. The only mild overlap is between find_polity and world_at_year, but their descriptions clarify different access patterns (name/QID lookup vs. temporal/geographic listing).
All names use snake_case and are readable, with three following a verb_noun pattern (create_video_link, find_polity, search_events). world_at_year deviates by being a noun phrase rather than starting with a verb, but the overall convention remains clear.
Four tools are well-scoped for a focused historical map video link generator and data lookup service. Each tool earns its place without redundancy, and the count is comfortably within the ideal 3–15 range.
The surface covers the core workflows: generating video links, finding polities by name/QID, searching events, and listing polities by year. Minor gaps exist, such as fetching individual event details by ID or resolving arbitrary place names, but agents can work around these using the provided lookup tools.
Build a link that opens RewindMap's short-video maker preloaded with a map clip: borders (and optional event layers) changing from one year to another over a place, with an optional title and map labels. The visitor opens the link and taps Download to get a watermarked MP4 (vertical 9:16 for Shorts/Reels/TikTok, or landscape). Rendering happens in the visitor's browser; this tool returns the link only, never a video file.
| Name | Required | Description | Default |
|---|---|---|---|
| bbox | No | Area to frame [west, south, east, north] in degrees. Default: Europe and the Mediterranean. | |
| title | No | Text burned into the top of the video. | |
| format | No | vertical | |
| labels | No | Map labels drawn at fixed points in every frame. | |
| layers | No | Layers shown in the clip. | |
| seconds | No | ||
| to_year | Yes | Year. Negative is BC: -500 = 500 BC. There is no year 0. | |
| from_year | Yes | Year. Negative is BC: -500 = 500 BC. There is no year 0. |
Look up a state or empire by name or any of its Wikidata labels and aliases (substring, case-insensitive), or by Wikidata QID. Returns its lifespan, every border snapshot with its bounding box, and links.
| Name | Required | Description | Default |
|---|---|---|---|
| lang | No | Site language for returned page and map links. Use the language the user is writing in. | en |
| query | Yes | Name, e.g. "Ottoman", or a QID, e.g. "Q12560". |
Search map events: battles (Wikidata), UCDP armed-conflict events since 1989, volcanic eruptions VEI 4+ (Smithsonian GVP), significant earthquakes (NOAA), witnessed meteorite falls, and UNESCO World Heritage sites (undated). Month/day bounds match only events recorded at least that precisely; undated heritage sites match only searches without a date bound. Results are sorted by date.
| Name | Required | Description | Default |
|---|---|---|---|
| bbox | No | Bounding box [west, south, east, north] in degrees. | |
| lang | No | Site language for returned page and map links. Use the language the user is writing in. | en |
| layer | No | ||
| limit | No | ||
| query | No | Substring of the event name or detail, e.g. "Vienna". | |
| to_date | No | Source-calendar date fields at month precision, or day precision when day is supplied. Historical sources may use Julian dates; bounds compare their recorded fields without calendar conversion. | |
| to_year | No | Year. Negative is BC: -500 = 500 BC. There is no year 0. | |
| from_date | No | Source-calendar date fields at month precision, or day precision when day is supplied. Historical sources may use Julian dates; bounds compare their recorded fields without calendar conversion. | |
| from_year | No | Year. Negative is BC: -500 = 500 BC. There is no year 0. |
List states, empires and cultures with an OpenHistoricalMap border snapshot in a given year, optionally overlapping a region. Coverage is incomplete; an empty result does not establish historical absence.

| year | Yes | Year. Negative is BC: -500 = 500 BC. There is no year 0. |
