Why this record matters
“Timeline of the history of the United States (1970–1989)” is worth following because a concise public description often conceals a longer documentary argument. Here, Timeline, history and United provides the most credible route into that argument.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Sep 23, 2026. The linked authority identifier is Q7805970. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1970, 1989 and 1971.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
