Mulled wine or Gluhwein is a very old drink. There is evidence that it dates back to the Romans in the 2nd century BCE. Now, it is popular across Europe, but especially in German-speaking countries over the Christmas holidays. I have included all of the ingredients popular in mulled wine. I encourage you to go by your personal tastes and make a drink unique to you. If you must have a recipe, there are hundreds online. Once you have a good combination, just warm it in a saucepan or crockpot and serve.
