Historic vs. Historical
“Historic” normally means important or likely to be important in history. “Historical” means connected with the past, history, or the study/representation of past events.

Quick tests
Meaning / construction test
Do you mean “historically significant,” rather than simply “related to history”?
If yes: Use “historic.”
If no: Use “historical” for the broader “related to history/the past” meaning.
Caveat: The distinction is semantic rather than absolute collocation; context determines whether significance or general relation to history is intended.
Examples
The agreement was a historic milestone.
“Historic” marks historical significance.
The archive contains historical maps.
The maps relate to the past; they need not be historically significant themselves.
Researchers compared the current figures with historical data.
“Historical” describes data from or relating to the past.
Usage notes
Alternative wording may be valid when the intended meaning changes; this is not an editorial-only preference.
Further guidance
Meaning Boundary
A historic event is historically important; a historical event is simply an event from or connected with the past.
Overlap Warning
Some real sentences can support either adjective with a different intended emphasis, so the engine should not label every alternative as an error.
