A palanquin is like a little bed on poles that people used to carry other people around on. Imagine you're playing a game of pirates and your friend gets hurt and can't walk. Instead of carrying them on your back, you could put them in the palanquin and carry them around like a king or queen! It's kind of like a portable chair, but fancier with curtains and sometimes even decorations on it. In old times, important people like kings and queens would use a palanquin to travel long distances because it was more comfortable than walking or riding in a bumpy carriage.
