Sremski Karlovci
Until 1989 Sremski Karlovci formed one of the urban municipalities of the city of Novi Sad. After Novi Sad merged six of its municipalities into one "Novi Sad municipality", the municipality of Sremski Karlovci held a referendum to separate from Novi Sad, and established a separate municipality independent from Novi Sad. Although Sremski Karlovci lies in Syrmia region, the municipality belongs in South Bačka District, and not in the Syrmia District, because of its close proximity to Novi Sad.
