By former country template i mean the "former country infobox", with the flags, basic info, names etc. I bet you are familiar with those. 
I think i got your problematism with the "history" section being used for countries/territories, which no more exist (like the present Gaza occupation article). Since there is no clear rule on this (in addition to previously shown examples there is also the Coalition Provisional Authority article with history section) though i don't feel and passion on using "history" title, can we agree on "chronology" or "timeline"?
