1. The early era (the League's faces): the post-WWI displacement (the Russian-and-Armenian refugees; the Nansen passport (the first international identity document — the League's machinery; the High Commissioner's office 1921)).
2. The WWII-and-1951: the war's displacement (the 40-million's tragedy); the IRO's bridging; the 1951 Refugee Convention (the definition-and-rights core) — the Eurocentric limitation (the time (the pre-1951 events) and the place (the European faces)).
3. The 1967 Protocol — the universalisation (the limitations removed).
4. The regional expansions (1.3's detail).
5. The institutional line: UNHCR (1950's creation; the mandate's growth); the ILO-and-IRO predecessors.
6. The modern era: the mixed-migration-and-protection debates (U5); the compact era (2016- and-2018); the climate-displacement's frontier.
