Upon some research for the time periods I’m writing in, for example in Old English (and prior to that) there were no capitalisations, but plenty of titles, due to the glyphs that were mostly all uppercase or otherwise all lowercase, so it’s my choice as the writer to include capitalisation or not I suppose, but for later time periods, if you want to sound authentic, then again, it’s the choice of the author.
