Germany is another reenactor-friendly country that hosts some great groups and interesting time periods. They reenact most of the conflicts close to home soil (barring WW2 for obvious reasons) like the Franco-Prussian War, or far away conflicts like the American Civil War. Les Zouaves cuts across many time lines from the 1840's to WW1 - with the same type of impression.
It's a very interesting site, especially if you're a Zouave fanatic, or would like a window into European reenacting, which is always a nice treat. The site has plenty of pictures of all the group's covered time periods. Incidently, the fellow to the left is a Franco-Prussian War Zouave.
