10 June 1288 in a charter of the Sovereign Military Order of Malta command in Rheinfelden. The village name may have its origins from an Alamanni tribal leader called Zuzo. An important early landowner was the monastery of Bad Säckingen. The first known rulers were Habsburgers. After the Waldshut war of 1468 the whole Fricktal was pledged to the Duchy of Burgundy. The Burgundians were crushingly defeated by the Old Swiss Confederacy during the Burgundian Wars meaning that Hellikon was restored to Austrian (Habsburg) authority by 1477. Following the country reforms of the Austrian King Maximilian I., Hellikon fell under the authority of "Further Austria" in 1491. The Möhlinbach territory (including Hellikon) came under the administration of the Kameralherrschaft Rheinfelden. During the 17th century, there was very little time when peace prevailed. During the Rappenkrieg, a peasant uprising that lasted from 1612 until 1614, and the Thirty Years' War (1633–38) the village's economic development went into decline. Also during the Pfälzer-Erbfolge Wars (1688–97) foreign troops passed through the region. As a result of the Treaty of Campo Formio in 1797, the Fricktal became a French protectorate, forming the front line between the French Revolutionary and the Austrian troops in the War of the Second Coalition. On 20 February 1802, Rheinfelden was made a district capital of the newly created Canton of Fricktal, (Principality of Frickgau), joining the Helvetic Republic in August. On 19 February 1803, Canton Fricktal, including Zuzgen, was absorbed into Canton Aargau. On 2 July 1801, a large fire destroyed almost all the houses in the village. Additionally epidemics and crop failures followed, forcing many inhabitants away. Other than farming there were few employment opportunities (for instance a small thread mill). For decades the population remained stable or slightly dropped. At the beginning of the 1980s strong building activity started, and ever more people moved from Basel and its suburbs into the village. The population has since grown by over 50%. Notable sights At the upper entry to the village two churches stand opposite one another, the Christ Catholic St. Georg in Barock style and the Roman Catholic St. Georg in Neogothic style.
