This is info on all of the hetalia google history blogs on tumblr (made by Gaul). All countries can be found in one of the tabs above depending on what group they are under. Not all the blogs may be active but there are hyperlinks for all the ones I find on tumblr. I know all the blogs aren't here but I'm trying my best to find them all and put them on here.
If you have a problem you can message Gaul on tumblr.
