The Walk Crisis (also called the Valga Crisis or the Valka Crisis, after the Estonian and Latvian names of the town respectively) was an episode in Estonia–Latvia relations over the territorial dispute along the border between the two countries, chiefly about the town of Walk (now Valga, Estonia and Valka, Latvia) and the island of Runö (now Ruhnu, Estonia). The territorial dispute lasted from both countries' independence in 1918 until its settlement in a border agreement in October 1920.
