The area around Zuzgen is known to be settled in Roman times; coins and the remains of a wall provide evidence. The Alemanni (an alliance of Germanic tribes) left their mark with well-preserved graves. The first documented mention of Zuzchon dates from 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.
