Galliano was created in 1896 in Italy, though currently it's produced in France, and it's named after an Italian war hero. It's made up of about 30 herbs and spices, and it has a sweet mild anise flavor with spice in the finish. It's quite tasty as a sipper, but it's good that it comes in a 375 ml bottle since it could take a while to finish it. I've only found one good recipe that uses Galliano (from Food & Wine Cocktails, 2010) and my adaption of it is below.
Mistral
1 1/2 oz lemon vodka
1/2 oz Lillet (or Dubonnet blanc)
1/2 oz Galliano
1/2 oz limoncello
2 dashes Peychaud's bitters
1 orange twist
Muddle the orange twist, then shake everything with ice.
