In the 9th century, the territory of Rohovce became part of the Kingdom of Hungary. The village was first recorded in 1250 as Zerva. Until the end of World War I, it was part of Hungary and fell within the Somorja district of Pozsony County. After the Austro-Hungarian army disintegrated in November 1918, Czechoslovak troops occupied the area. After the Treaty of Trianon of 1920, the village became officially part of Czechoslovakia. In November 1938, the First Vienna Award granted the area to Hungary and it was held by Hungary until 1945. After Soviet occupation in 1945, Czechoslovak administration returned and the village became officially part of Czechoslovakia in 1947. Its Slovak name first became Velka Sarva, which was changed by the authorities to the current official name in 1948.
