|county of Ancient Estonia|
Sakala County is in northwestern Livonia, covering approximately the present counties of Viljandi, the southern half of Pärnu and the western third of Valga County. It was the southernmost of the ancient Estonian counties.
According to one hypothesis, the tribe of Sosols mentioned in Old East Slavic chronicles implies the people of Sakala. The chronicles say that Kievan Rus organized military campaign against Sosols in 1060 and taxed them. A year later, Sosols rose, destroyed Kievan Rus fort in Tartu and attacked Pskov.
In Sackalian folklore, the neighbouring Ugaunians (ugalased) were enemy warriors and robbers. For instance, a folk song from Viljandi, the capital of Sackalia, calls for speeding up the harvest work because the Ugaunians might attack.
