UK History: Chapter 2, Exercise 1 — Possible Solution
======================================================================

EXACT OR STATED PLAINLY
43 CE: invasion under Claudius. 77 to 84: Agricola's expansion. 410: the
withdrawal.

APPROXIMATE
60 or 61: Boudica's revolt (two possible years). About 122: Hadrian's Wall.
About 142: Antonine Wall. About 197: division into two provinces. About 312:
four provinces.

ON 410
CAN CLAIM: Roman withdrawal, and that a letter of Honorius is traditionally
interpreted as rejecting British appeals for aid.
CANNOT CLAIM: the exact nature of the transition (debated), or how life
changed afterwards (I did not research it).
