The Dutch Reformed Church (Dutch: Nederlandse Hervormde Kerk, pronounced [ˈneːdərlɑntsə ɦɛrˈvɔr(ə)mdə ˈkɛr(ə)k], abbreviated NHK [ˌɛnɦaːˈkaː]) was the largest Christian denomination in the Netherlands from the onset of the Protestant Reformation in the 16th century until 1930. It was the traditional denomination of the Dutch royal family and the foremost Protestant denomination until 2004, the year it helped found and merged into the Protestant Church in the Netherlands (the largest Protestant and second largest Christian communion in the Netherlands). It was the larger of the two major Reformed denominations, after the Reformed Churches in the Netherlands (Gereformeerde kerk) was founded in 1892. It spread to the United States, South Africa, Indonesia, Sri Lanka, Suriname, Brazil, and various other world regions through Dutch colonization. Allegiance to the Dutch Reformed Church was a common feature among Dutch immigrant communities around the world and became a crucial part of Afrikaner nationalism in South Africa.

The Dutch Reformed Church was founded in 1571 during the Protestant Reformation in the Calvinist tradition, being shaped theologically by John Calvin, but also other major Reformed theologians. The church was influenced by various theological developments and controversies during its history, including Arminianism, the Nadere Reformatie, and a number of splits in the 19th century that greatly diversified Dutch Calvinism. The church functioned until 2004, the year it merged with the Reformed Churches in the Netherlands and the Evangelical Lutheran Church in the Kingdom of the Netherlands to form the Protestant Church in the Netherlands (PKN), a united church of both Reformed and Evangelical Lutheran theological orientations. At the time of the merger, the Church had 2 million members organised in 1,350 congregations. A minority of members of the church chose not to participate in the merger and instead formed the Restored Reformed Church (HHK).

World War II in the Netherlands can be broken down into 4 periods:

• September 1939 to May 1940: After the war broke out, the Netherlands declared neutrality. The country was later invaded and occupied by Germany.
• May 1940 to June 1941: An economic boom caused by orders from Germany, combined with the "velvet glove" approach from Arthur Seyss-Inquart, resulted in a comparatively mild occupation.
• June 1941 to June 1944: As the war intensified, Germany demanded higher contributions from occupied territories, resulting in a decline of living standards in the Netherlands. Repression against the Jewish population intensified and thousands were deported to extermination camps. The "velvet glove" approach ended. Meanwhile the Netherlands's East Indies possession in Asia was invaded and occupied by Japan.
• June 1944 to May 1945: Conditions in the Netherlands deteriorated further, leading to starvation and lack of fuel. The German occupation authorities gradually lost control over the situation. Nazis wanted to make a last stand and commit acts of destruction, others tried to mitigate the situation, until the country was finally liberated by the Allies. In the East Indies, Japan continued to occupy it until its surrender months later.

Despite Dutch neutrality, Nazi Germany invaded the Netherlands on 10 May 1940 as part of Fall Gelb (Case Yellow). On 15 May 1940, one day after the bombing of Rotterdam, the Dutch forces surrendered. The Dutch government and the royal family fled to London. Princess Juliana and her children sought refuge in Ottawa, Canada, until after the war.

The Glass Coach (Dutch: Glazen Koets) is a royal carriage that was used by the Dutch royal family for special events before Queen Wilhelmina received the Golden Coach. The coach was then used only for the monarch or the parents of the bride or groom on a royal wedding day. In 2015, it started to be used more frequently for state events because the Golden Coach needed to be repaired. It is the oldest coach the Dutch royal family owns. The Glass Coach is stored at the Royal Stables in The Hague.

In the Kingdom of the Netherlands, the monarchy of the Netherlands is a constitutional office and is controlled by the Constitution of the Netherlands. A distinction is made between members of the Dutch royal family as a whole and members of the royal house in particular. Both the royal house and the larger royal family are part of the Orange-Nassau dynasty.
