The words historical and historic were synonymous to each other back in the 18th century meaning something that belonged to or is representative of the past. Historic was used as a shortened form of historical but the difference between the two started diverging over time. In the early 19th century, the difference between the two had solidified and so did the confusion and misinterpretation of both the words.

The ‘al’ at the end of historical starts with an a and so does ‘all’, so historical is for all the events of the past.
