What made King Louis IX of France famous? URGENT?

Doing a Google search for biography "Louis IX" would do the trick nicely. Learning how to use search engines so that you find what you want easily and quickly, is a fine art. Two things which help are: 1) using the - sign to exclude words and phrases you don't want to see: sometimes you do a search, and one particular thing comes up again and again, cluttering up the place. You can just put a - sign in front of the unwanted word of phrase, and it goes away!! For example -movie means you won't see the word movie in any of the search results. 2) Put phrases in quotation marks, which makes the search engine treat them AS phrases, and not as just dissociated words. "leadership review" will bring up the phrase "leadership review" specifically, and not just the words leadership and review separately. and 3) If you don't find what you are looking for at first, keep on trying: soner or later you'll enter the correct words and phrases which will find you what you are specifically seeking.
