From the second half of the 17th century Poznań, like Poland as a whole, suffered from a series of invasions and other disasters. The city was occupied by a Swedish army in 1655 during the Second Northern War, replaced by Brandenburgians in 1656 (the Swedes burned the suburbs when they left). The Brandenburgian garrison surrendered after a two-month siege in 1657, which left the city devastated. There were also many deaths from plague during this time. In the Third Northern War Poznań was again occupied by a Swedish army, from 1703–1709, and became the main centre of the pro-Swedish movement in the country. After 1709 the city was occupied by Saxon forces, who looted much property; there were also further outbreaks of plague until 1711. The city was captured by forces of the Tarnogród Confederation in 1716, which led to further plundering. Russian forces arrived in the region in the same year (remaining until 1719), but accepted payment not to enter the city.
