The town was first mentioned in a 15th-century source as Uradmur. The current form appears for the first time in a source from 1488. The name is derived directly from the personal name Radomir or its adjectival form. In 1918, Bulgaria was ruled by Ferdinand of Bulgaria, under whom Aleksandar Stamboliyski had been imprisoned for opposing Bulgaria's participation in the Balkan War and its alliance with the Central Powers in World War I. When in September the Allied forces broke into Bulgaria, Ferdinand agreed to release Stamboliyski in return for a promise to help restore order in the military. However, Stamboliyski instead aligned himself with the uprising and in Radomir proclaimed Bulgaria to be a republic. His supporters then attempted an attack on Sofia. The Radomir Rebellion was stopped when this force was defeated by Bulgarian and German tsarists, who also did not retain control for long as Bulgaria had signed an armistice with the Allies by the end of the month.
Places of interest
The village of Baykalsko is a quiet and beautifully preserved natural settlement. The old church of Sveta Bogoroditsa, partially destroyed and rebuilt in the 19th century, has a recently restored, historic bell tower. A new cemetery bears the remains of generations on the opposite side of the village. The mayor's office and the post office are located across from the church of Bogoroditsa. The village is home to fewer elderly people and a growing population of seasonal visitors. Natural trails leading in and about nearby Konyavo Mountain, and the Choklyovo Marsh, are tourist attractions of Baykalsko. The old name of the village, Choklyovo, has not been restored to date. The marsh of Choklyovo is a preserved area, as it is the natural habitat of rare bird species and a repository of therapeutic mud. The village overlooking the lake consists of small houses traditionally made of mud and sticks. There is some small-scale construction from the 1970s and 1980s and several newer villas. Legend has it that a Medieval ruler, settled opposite the lake, issued a decree for all houses to face in his direction. Baykalsko may be reached by bus from Sofia or Kyustendil, or by train via Zemen. Bed & breakfast accommodations are available by arrangement.
Radomir was also the name of a Bulgarian prince. Radomir was the surname of Gavril Radomir of Bulgaria, who ruled Bulgaria from October 1014 to August 1015.
