Nağaybäk cavalry participated in the Napoleonic Wars and in the subsequent occupation of Paris. In 1842, the Nağaybäk cossacks relocated from their former host in Nagaybak Fort eastward, to the former Orenburg Governorate. Here, they founded a chain of villages named after the battles of Napoleonic Wars, including present-day Parizh, named after the Battle of Paris in 1814, Fershampenuaz (after the Battle of Fère-Champenoise), Kassel (after engagements near Kassel in Hesse), Trebiy (after the Battle of Trebbia) in 1799, etc. Fershampenuaz remains the center of Nagaybaksky District to present. Another group of the Nağaybäk settled in present-day Orenburg Oblast. These Nağaybäks settled on traditionally Muslim territories, and by the beginning of the 20th century they converted back to Islam and were reassimilated into Tatar ethnos.
