As we know, the Mongols were a largely nomadic people during their conquests and subsequently lived in yurts, called gers in Mongolian. I am curious as to what the yurts of Genghis Khan and other high-ranking Mongols were like. Were they mobile palaces, filled with jewels, carpets, and other luxury items from their victories? Or were they simply utilitarian living spaces?
Not to discourage other answers, but I (u/thither_and_yon) wrote a short answer on this last year. They were extremely palatial! William of Rubruck, a European traveler, described Guyuk Khan using a tent which rested on pillars covered in gold plates and fastened with golden nails.
Another detail I don’t think I mentioned last time was the semi-nomadic city life of the Mongols, most famously at Karakorum. There are lifestyles in between complete nomadism and settled life where you return to the same locations at given times of year or for given occasions, and the Mongols definitely did this under the Chinggisids (Genghis Khan and his descendants). This allows for a more monumental and easily assembled tent city, because you can build earthwork foundations and walls that remain permanently on site, while some or most of the structures and their occupants travel with the herds and/or armies.
