Where it sits in time
Five thousand years, 3000 BCE to 2026; the state in gold.
How it ended, as its article says
Replaced by House of Habsburg, 1516. Read from the article's section “lead” by its grammar; the claim is only that the article says so.
The dynasty was replaced by the House of Habsburg upon the effective enthronement of Charles V as king of Castile and Aragon in 1516, even though his mother Joanna lived (imprisoned and with deteriorating health) until 1555.

What led to it, and what came of it
The investigation's own picture: 1 cause the record names and 0 results, the strongest six of each at their own years, joined to the state by the kind of claim - a recorded statement solid, the article's sentence dashed, a theory dash-dot.
Open the investigation: every row with its evidence, the conditions at the time, the theories condition by condition, and the succession analysed.
