I'll just give a bit of explanation of the Dutch things, because history is fun!
Queen Wilhelmina: First Queen of the Kingdom of the Netherlands (well, unless you count Emma, but she was a regent for Wilhelmina technically). She is most famous for the Second World War, where she fled to England when the nazi's invaded. From there she became heavily involved with the Dutch resistance. There are more than 200 streets named after her (only counting -straat, not counting -road, -drive etc.).
Grote Rivieren (lit. Big Rivers): The three main rivers of the Netherlands are called 'de Grote Rivieren': the Rhine, Meuse and Waal. Because the Netherlands is situated in a river delta, these rivers have been historically important as trading routes, and remain important until this day, helped by the Port of Rotterdam (the largest port in Europe). The Grote Rivieren also function as a cultural divide, with 'Boven (above) de Rivieren' and 'Onder (below) de Rivieren' as a way of saying 'Northerner' or 'Southerner'
Polder: Around 17% of the country is made up of polders, land that has been reclaimed on water. Most of them used to be lakes (like the Haarlemmermeerpolder, where the main airport Schiphol is located), but the most famous (and biggest) is Flevoland, an entire province which has reclaimed. The Afsluitdijk now is the barrier between the sea and the (new) lake. In the lake, a part is drained to form Flevoland.
De Zeven Provinciën (lit. the Seven Provinces): This is the name of a bunch of ships, but looking at the model in-game, they probably mean
this one. This used to be Michiel De Ruyter's main ship when he kicked the English' butts in the Second Anglo-Dutch War (1665-67). The name comes from the fact that the Netherlands used to be a republic of seven united provinces (Holland, Utrecht, Friesland, Groningen, Zeeland, Gelderland and Overijssel), after defeating the Spanish in the Dutch Revolt.
Radio Oranje (lit. Radio Orange): This was the main line of communication between the London government-in-exile and the Dutch Resistance during the Second World War. Queen Wilhelmina gave famous speeches on this radio channel, that could only be listened to via illegal radio's (the nazi's had confiscated all radio's at this point). The Queen was first seen as a coward for fleeing to London, but with her speeches, she became very popular once more. The name Orange comes from the French town of Orange. William of Nassau inherited this Principality, becoming William of Orange-Nassau (van Oranje-Nassau, also known as William the Silent). This lead to the royal family (yes, during the republic we had a (kind-of) royal house still. It was very confusing) becoming known as 'the Oranjes'. This is also why Dutch athletes wear orange during their matches.
