Yes
Belgium probably use to be our allies because long time ago the Americans were basically fighting against everybody who were not on their side because they were fighting over North America. That was during the civil war. I'm not a 100% positive.
At the start, the 'Triple Entente' of Britain, France and Russia. They were joined by Belgium (invaded by Germany) Serbia and Greece. Italy entered the war on the side of the Allies in 1915 and the USA in 1917. Japan also fought on the allies side.
Czechoslovakia was formed after WW1 and therefore took no side in the conflict.
The side of the Allies .
He was on the allies side.
Yes Great Britain was an ally to France and Belgium.
Belgium and France.
I think they are the Netherlands and Luxembourg.
I believe so... Germany invaded Belgium even though they remained neutral more info at http://militaryhistory.suite101.com/article.cfm/the_belgian_army_of_1914_
During World War I, Belgium's primary allies were the Entente Powers, which included France, the United Kingdom, Russia, and later Italy and the United States. Belgium was invaded by Germany in 1914, prompting the UK to declare war on Germany due to its commitment to defending Belgian neutrality. Throughout the war, Belgium received support from these allies in terms of military aid and resources.
I think Belgium have more to do with The Netherlands and Luxembourg (the BENELUX countries) but I also think that during World War 2 the whole of Europe became allies. Except for Germany and Italy of course.
All joins allies side.
