Kaiserwerth, officialy the Canton of Kaiserwerth (Hunsrik: Kanton von Kaiserwerth; Portuguese: Cantão de Kaiserwerth) is a Neo-Rhenish canton enclaved in the Brazilian city of Blumenau, within the state of Santa Catarina. Its capital is the city of Barbarossa, which is country's largest city and also serves as the capital of New Southern Rhine. The canton is also home to the city of Hohenstaufen. The canton is administered by a Steward appointed by the monarch and is divided into two municipalites, Barbarossa, the capital, and Hohenstaufen.
The territory that makes up the modern-day canton was inhabited by the Xokleng Indians until the 16th century, when it was conquered by the Portuguese and annexed to Brazil. German, Austrian and Swiss immigrants settled in the region at the beginning of the 19th century, when it was a captaincy and subsequently a province of the independent Brazilian Empire. During this same period, the Scherer family settled in the region. In 2021, influenced by micronationalism, Jonathan Scherer-Arrais proclaimed the independence of his family properties and founded Independent State of the New Southern Rhine. His family's properties in the Brazilian city of Blumenau were converted into the Neo-Rhenish canton of Kaiserwerth.
