Historical / dissolved entities and their successor states

A curated crosswalk from dissolved entities (Soviet Union, Yugoslavia, Czechoslovakia, ...) to the modern states that succeeded them – one row per (entity, successor) pair, dated, so historical panels can be brought onto the modern ISO spine honestly instead of being silently dropped (or worse: countrycode resolves "USSR" to Russia alone). Consumed by dissolve_country() and flagged by check_country_match().

Usage

historical_codes

Format

A tibble with one row per (entity, successor):

historical

Canonical name of the dissolved entity.

iso3c_hist

The alpha-3 code the entity held at dissolution, where one existed (SUN, YUG, CSK, DDR, ANT, SCG, YMD, ...); it may since have been inherited by a successor (e.g. YEM).

dissolved

Year the entity ceased to exist.

iso3c, country

The successor state.

Source

Curated from ISO 3166-3 and the historical record.

Details

Kosovo (XKX) is included among the Yugoslavia and Serbia-and-Montenegro successors on a territory basis (its territory was part of both); filter it out if your analysis follows strict UN-membership succession.
