After the declaration of the Kingdom of Prussia in 1701, the situation in the Neumark began to improve. King Frederick I initiated new waves of colonization. Many French Huguenots, forced to flee from religious persecution in France, arrived as settlers. The textile industry also began to develop in the Neumark. The Seven Years' War caused the region to regress in its development, as high contributions were exacted from the population for the war effort and the Neumark was the setting for battles such as at Kunersdorf. Under Frederick II, increased land reclamation and economic consolidation resulted from the drainage of the Warta and Notec areas.
