Strategic Narrative Overview
The crisis unfolded as a diplomatic and at times tense territorial standoff rather than a full-scale military conflict. Both Estonia and Latvia were simultaneously engaged in their respective wars of independence against Bolshevik and other forces, limiting their capacity for direct confrontation with each other. Negotiations over the border proceeded intermittently, complicated by the strategic and economic importance of the Walk railway junction and the mixed population of the disputed town and surrounding areas.
01 / The Origins
When Estonia and Latvia both declared independence in 1918 following the collapse of imperial Russian authority, they inherited overlapping territorial claims along their shared border. The most contentious point was the town of Walk, known as Valga in Estonian and Valka in Latvian, which straddled the prospective border. The island of Runö (now Ruhnu) was also disputed. Neither newly formed state had clearly demarcated boundaries, producing immediate friction between two allied nations simultaneously fighting for survival.
03 / The Outcome
The dispute was settled through a bilateral border treaty signed in October 1920. The town of Walk was partitioned along the Pedeli River, with the southern portion (Valga) assigned to Estonia and the northern portion (Valka) to Latvia. Ruhnu island was awarded to Estonia. The agreement established a durable international boundary and normalized relations between the two newly independent Baltic states in the immediate postwar period.
