Invited through a manifesto issued by Catherine the Great, several families from this region travelled to Russia in the late 18th century to settle in the Volga Region near Saratov. Family names Daubert, Pfaffenroth and Scheuermann are examples of Volga Germans who helped to establish local villages, including Yagodnaya Polyana.
Nidda has a vibrant mix of people from many backgrounds, including Turkish, Russian and Pakistani. The Ahmadiyya Muslim Jamaat opened its first purpose-built mosque in Nidda in 2011.
