Footnote 2 - The German Empire and the Dutch Republic
Both the Germans and the Dutch belonged to the Teutonic or Germanic Race. In the Middle Ages the German Empire was very large indeed and included the provinces (seventeen in total) of the Low Lands or the Netherlands (Nether = Low) - today's Kingdom of the Netherlands and the Kingdom of the Belgians. The German Emperor appointed a vassal or 'liegeman' to each of his provinces, often an appointment for life. So, when a liegeman died, a new one was appointed in his place. But in the vast empire, and in particular in the 17 provinces, the vassals soon forgot that they were liegeman and saw to it that they were succeeded by their eldest son. There was little the German Emperor could do about it. The liegemen took titles such as 'Duke' or 'Count' and even tried to enlarge their territories by fighting their neighbouring liegemen.
In 1555 Charles V died. He was the elected Emperor of the German Reich, King of Spain and Lord of all the 17 Provinces of the Netherlands. As King of Spain and Lord of the Netherlands his son Philip succeeded him. Charles had been born and bred in the Netherlands and felt some affinity with its population. Not so Philip, who had been born and educated in Spain and was a very proud and religious Spaniard, who despised his northern subjects and their 'barbaric' language. Overruling any influence on the government that the inhabitants of the 17 provinces had had, he ruled them from Spain and considered and treated the provinces as Spanish colonies.
Meanwhile, the Reformation had begun and Philip was very much opposed to the protestant religions, which had taken root in the 17 provinces. He decided to wipe them out. He sent a Spanish army to support the Inquisition, so inflaming his subjects that they revolted and in 1568 the War of Independence, which was to last for 80 years, began. In 1581, 7 of the northern provinces rejected Philip as their ruler, declared their independence, and created 'The Republic of the Seven United Netherlands'. In 1648, the Westphalian Peace Treaty was signed in the German city of Münster. Both Spain and the German Emperor had to recognise the independence of the Republic, which now no longer belonged to either Spain or the German Empire. The Republic was to last until 1795, when it was changed from a Federal Republic into a National Republic, with a central government in The Hague (Den Haag).
Detached from the German Empire and fully independent, the country and its people drifted away from the Empire and developed separately. The formerly spoken Lower German dialects fell into disuse and the Dutch language came to being which, 200 years later, differed greatly from the German dialects on which it was based. Moreover, Germany was an almost land-locked country, whereas the Dutch (like the Britons) had become a seafaring nation. Their sailors and traders were discoverers, adventures and even colonisers. They had an open mind, investigated everything foreign, and adopted the things they found that they liked. The Republic also knew total freedom of religion and became a refuge for many that were persecuted in other countries, such as the Flemish and French protestants, the British Pilgrim Fathers, and the Jews.
In 1940 there was a wide gap between the Netherlands and Germany. The Dutch never considered themselves as being 'Lower Germans' anymore. (More on this.) Hardly anyone remembered that once their territory had belonged to the German Empire.
