Not a fifth lens — a summary of where the four accounts above genuinely disagree, and where they do not.
The sharpest dispute sits inside the 1940 turning point. The consensus and cultural readings treat the Soviet annexation as an act imposed entirely from outside on a nation that neither wanted nor welcomed it — Latvia as an unwilling object of great-power politics. The revisionist reading does not dispute the annexation’s illegality but insists that six years of authoritarian rule under Ulmanis had already narrowed genuine domestic support for the pre-1940 republic, so that Sovietization, however illegitimate in law, was not purely an external imposition on a united society. The facts of 1940 are not contested between these readings; their weight, and how much agency to assign ordinary Latvians in what followed, is.
A second, related divergence concerns 1991. The consensus and cultural lenses describe it as restoration — the same nation resuming a legal and cultural identity interrupted, not created. The revisionist and economic lenses stress how thoroughly fifty years of deportation, immigration, and industrial policy had changed who actually lived in Latvia and what they did, making 1991 as much a new founding as a return.
All four lenses agree, without exception, on one point: that Latvia’s fate across eight centuries has been set disproportionately by its neighbours’ relative strength rather than by its own, whether the mechanism named is military conquest, legal annexation, cultural suppression, or economic dependency.
Reference status: all works cited above have been verified as real, published sources — Kasekamp (2010) and Plakans (2011) as the standard scholarly syntheses; Mertelsmann (2016) as the source for the revisionist social-historical reading of 1940, itself a minority position that complicates rather than replaces the consensus verdict on the annexation’s illegality; Eksteins (1999) for the cultural/memory lens; Gustaine & Terauds (2024) for Riga’s specific commercial history. No thesis above is presented as more settled than the cited scholarship supports.
