the region developed its next major agricultural commodity. In the 19th century, Kecskemét was already part of an important wine district, but the city increased in importance after the vine-pest destroyed most vineyards in the hilly regions. Damage was less significant in the plains' areas of loose, sandy soil. In the 1870s, landowners planted large plantations of grapevines around the town. These were the basis of the 20th-century vineyards and wine industry of the 20th century in Kecskemét.
