The Northern Wars (1655-1661) is a name sometimes used for the series of conflicts between Sweden and its adversaries Polish-Lithuanian Commonwealth (The Deluge, 1655-1660), Russia (1656-1661), Brandenburg-Prussia (1657-1660), the Holy Roman Empire (1657-60) and Denmark (1657-1658, 1658-1660). The same wars are sometimes referred differently in other countries: for example in Poland The Deluge sometimes is a name for the series of war against Sweden, Brandenburg, Russia, Siebenbürgen and Cossacks.
The Seven-Year War was the conflict from 1592 to 1598 on the Korean peninsula, following two successive Japanese invasions of Korea.
Hideyoshi considered himself the victor in the war, and was enraged to find out that he was to be installed as a tribute-bearing vassal.
Farmlands were devastated, irrigation dikes were destroyed, villages and towns were burned down, the population was first plundered and then dispersed, and tens of thousands of skilled workers (celadon ware makers, craftsmen, artisans, etc) were either killed during the war or kidnapped to Japan as captives to help Japanese develop their crafts.
To a large extent, the early history of the Nordic region is a chronicle of struggles for power, wars and rivalry between neighbouring countries.
But in the past the Nordic countries have on many occasions displayed a willingness to co-operate, though it is impossible to state the exact date on which Nordic co-operation commenced.
The Nordic Council of Ministers was formed following the adoption of amendments to the Helsinki Treaty, which stipulated that the Council of Ministers was to serve as the official joint co-operation body for the Nordic governments.
