Bolnisi was settled by 95 German colonist families from Swabia in 1818, whilst part of the Georgia Governorate of the Russian Empire. Upon the arrival of the German colonists, the town was renamed Yekaterinenfeld (; ) in honor of the sister of Tsar Alexander I, Ekaterina Pavlovna, who was married to the King of Württemberg. Some eight years later, Yekaterinenfeld was pillaged by what were described as "Tartars", who burned down the German colony and massacred many of its inhabitants. In the early 20th century, Yekaterinenfeld had a mainly German and Russian population of 2,332.
