I couldn't let this go unchallenged. Although Genghis's forces touched Europe only relatively briefly, the impact elsewhere was much more long lived.
The Yuan dynasty in China, the Golden Horde in Russia and the Chagatid khanate all survived much longer, and both Timur (Tamerlane) and the Moghul empire link back to Genghis at least as directly as the European states link back to Charlemagne, and probably more so.
However, the OP asked for "favourite", and that is not the same as "most enduring", or "with the greatest impact". Genghis happens to be a fascination of mine, so is my favourite. If I had spent the same amount of time reading about the two Charlies or Alfie, I might feel differently.
