The film explains how the Ohio conflict expanded into the Seven Years' War and a global campaign, but a checksum-pinned caption, OCR, and scene-transition review found no discrete treatment of Britain's formal May 1756 declaration of war.

Why it matters
The Revolution's imperial prehistory was global: strategy, debt, trade, and territorial bargaining cannot be explained from the thirteen colonies alone.
Why this tier
Formal war joined regional violence to a world conflict, though it confirmed rather than initiated hostilities.
“French and Indian War” names the North American theater from a British colonial perspective. “Seven Years’ War” makes the global frame visible but can hide fighting before 1756; the site uses both with explanation.
