The town was destroyed twice during the Hussite Wars in 1425 and 1431. From 1526 with the Bohemian Crown it was part of the Habsburg Empire. Another great war disaster hit Lubawka when the Swedish army during the Thirty Years' War devastated the city which was abandoned by its inhabitants for more than six months. The city developed rapidly in the 18th century, particularly due to growth in the textile industry there and in surrounding villages. Unfortunately, several great fires damaged the city in those times. The largest one in 1734 destroyed the town hall, school, church, vicarage and almost all buildings.
