Swedish Livonia
During centuries, Suure-Jaani was one of the centres of Suure-Jaani parish (which was in 1629–1721 administratively a part of Swedish Livonia, in 1721–1918 a part of the Governorate of Livonia and as from 1918 a part of the Republic of Estonia) and, since the end of the 19th century, also the cultural and commercial centre of the parish region.
