They're not just horses; they're people of the low countries. And they were some of the first to bring back the republic after the collapse of the Roman Empire.
Those people from the modern day province of Frisia (or Fryslân), myself included, are called Frisians in English though. Same linguistic borrowing, but different time period, so the horses ended up Friesian and the people (and everything related to the province and historical region) Frisians.
Not sure what you mean by republic. Frisia became a kingdom after the collapse of the Roman Empire until the 8th century, after which the usual conquering and reconquering by various factions began.
