Ever wanted to play some more turns after WoI (War of Independence) without having that big white victory message on your screen permanently? 
I did, so I simply deleted the message text (but not the TAG itself!) in the relevant XML file. It's tested ingame and it works well, but it works however not with saved games (meaning games, that have been started and saved before making the changes in the XML).
Certainly, the change does not affect the "regular" victory message, you will still get the victory message pop up. But the annoying permanent white message will be gone.
How to do:
1. For regular game (no mod)
--> Look for the file CIV4GameTextInfos_Original.xml, direction is (...)Assets/XML/text
!!!! (in general, original files should NOT be changed, but if you do, please make a copy of the unaltered file!)
--> open the file with text editor (I use notepad++) and search (CTRL + f) for the TAG named TXT_KEY_MISC_WINS_VICTORY
--> simply delete all the text entries between the language tags as shown below:
before:
after:
--> save the file and the permanent victory message won't appear anymore.
2. For mods
Basically the same procedure as with the original file.
--> if the mod you play has its own CIV4GameTextInfos_Original.xml-file, you just make the changes in that particular file.
--> if the mod does not have the file, just copy the altered original file into (...)Assets/XML/text in the mod's folder structure
by the way: This also works for Civ4...
Have fun and a happy victory!
