Dutch people
By the middle of the 16th century an overarching, 'national' (rather than 'ethnic') identity seemed in development in the Habsburg Netherlands, when inhabitants began to refer to it as their 'fatherland' and were beginning to be seen as a collective entity abroad; however, the persistence of language barriers, traditional strife between towns, and provincial particularism continued to form an impediment to more thorough unification. Following excessive taxation together with attempts at diminishing the traditional autonomy of the cities and estates in the Low Countries, followed by the religious oppression after being transferred to Habsburg Spain, the Dutch revolted, in what would become the Eighty Years' War. For the first time in their history, the Dutch established their independence from foreign rule. However, during the war it became apparent that the goal of liberating all the provinces and cities that had signed the Union of Utrecht, which roughly corresponded to the Dutch-speaking part of the Spanish Netherlands, was unreachable. The Northern provinces were free, but during the 1580s the South was recaptured by Spain, and, despite various attempts, the armies of the Republic were unable to expel them. In 1648, the Peace of Münster, ending the Eighty Years' War, acknowledged the independence of the Dutch Republic, but maintained Spanish control of the Southern Netherlands. Apart from a brief reunification from 1815 until 1830, within the United Kingdom of the Netherlands (which included the Francophones/Walloons) the Dutch have been separated from the Flemings to this day.
Netherlands
The Netherlands were able to remain neutral during World War I, in part because the import of goods through the Netherlands proved essential to German survival, until the blockade by the British Royal Navy in 1916. That changed in World War II, when Nazi Germany invaded the Netherlands on 10 May 1940. The Rotterdam Blitz forced the main element of the Dutch army to surrender four days later. During the occupation, over 100,000 Dutch Jews were rounded up and transported to Nazi extermination camps; only a few of them survived. Dutch workers were conscripted for forced labour in Germany, civilians who resisted were killed in reprisal for attacks on German soldiers, and the countryside was plundered for food. Although there were thousands of Dutch who risked their lives by hiding Jews from the Germans, over 20,000 Dutch fascists joined the Waffen SS, fighting on the Eastern Front. Political collaborators were members of the fascist NSB, the only legal political party in the occupied Netherlands. On 8 December 1941, the Dutch government-in-exile in London declared war on Japan, but could not prevent the Japanese occupation of the Dutch East Indies (Indonesia). In 1944–45, the First Canadian Army, which included Canadian, British and Polish troops, was responsible for liberating much of the Netherlands. Soon after VE Day, the Dutch fought a colonial war against the new Republic of Indonesia.
In 1954, the Charter for the Kingdom of the Netherlands reformed the political structure of the Netherlands, which was a result of international pressure to carry out decolonisation. The Dutch colonies of Surinam and Curaçao and Dependencies and the European country all became countries within the Kingdom, on a basis of equality. Indonesia had declared its independence in August 1945 (recognised in 1949), and thus was never part of the reformed Kingdom. Suriname followed in 1975. After the war the Netherlands left behind an era of neutrality and gained closer ties with neighboring states. The Netherlands was one of the founding members of the Benelux, the NATO, Euratom and the European Coal and Steel Community, which would evolve into the EEC (Common Market) and later the European Union.
