Latvia's parliamentary system under the 1922 constitution had produced chronic governmental instability, with numerous short-lived coalition governments. Ulmanis and his allies argued that multi-party democracy had created chaos incompatible with effective governance, and they drew on broader European trends toward authoritarian rule to justify intervention.
On the night of 15–16 May 1934, Prime Minister Kārlis Ulmanis, backed by Minister of War Jānis Balodis and the paramilitary Aizsargi, seized control of key state offices, communications, and transport facilities. He declared a state of emergency, suspended the constitution, dissolved the Saeima and all political parties, and interned hundreds of opponents — all without armed resistance.
Ulmanis established a non-parliamentary authoritarian regime, eventually assuming the illegal title of State President in 1936. He governed without a ruling party or new constitution, instead creating corporatist Chambers of Professions. The regime persisted until Soviet forces occupied Latvia in June 1940, ending Latvian independence.
Political Outcome
Parliamentary democracy abolished; Ulmanis established authoritarian rule as Prime Minister and later illegal State President until Soviet occupation in 1940.
