Why this record matters
“1866” is worth following because a concise public description often conceals a longer documentary argument. Here, year 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 7, 2026. The linked authority identifier is Q7712. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1866, 1923 and 1864.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. 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.
