I want to write a document where the history, geography, culture of a certain place is the main text. Together with that, I want to present a timeline of events but, rather than a separated topic or chapter, the timeline should flow at the bottom of each page, independently of the main text of that page. And the timeline should not mess with possible footnotes the main text can have.
There is some way I can accomplish that?
Thanks in advance.
EDIT: A very rough sketch to attempt to clarify.

[b]option in a figure or table float with the timelines. By defaults this must allow only a bottom float per page. And you should read this question. What more? – Fran Jul 15 '19 at 23:26
