N before W, 5 before 15 — alphabetical order of commanders matches chronological order of battles.
Every testable date in chapters 2–5 of the handbook, organised by era. ⚓ Anchor dates are worth memorising first — every other date in an era can be positioned relative to one. Events flagged with a coloured tag belong to a sticky pair — recall those as pairs, not in isolation.

Decade-swap. Habeas Corpus (under Charles II) protects the individual from unlawful imprisonment. Bill of Rights (under William & Mary, post-Glorious Revolution) protects Parliament from the monarch. Individual first, then institution — ten years apart.

Both expand franchise.
Three franchise milestones. 1928 is the "fully democratic" date.
Wartime → post-war chain. Beveridge (1942) → Attlee elected (1945) → Bevan builds NHS (1948).
Late-20th-century political reorganization.
