who were there Green shirts in world war 2?

Answer 1

I never heard of any 'green shirts' in World War 2. Maybe you're thinking of the 'Brown Shirts', who were the SA, in Nazi Germany. They were basically members of the Nazi party who went around beating up members of other political parties who tried to make speeches in pre WW2 Germany. They lost a lot of their power in 1933, when Hitler had their leader, Rohm killed during the 'night of the long knives'. This enabled Hitler to become Chancellor of Germany. The Brownshirts had been causing so much trouble that President Hindenburg demanded that Hitler do something about it before he would name him chancellor. The SA (brownshirts) faded as a political force after this, and the SS and SD (Gestapo) took over the reins of power. They were called 'Brownshirts' because they wore a uniform consisting of a brown shirt and pants, with a coffee can hat.

Answer 2

And the original of the species was Italy's Black-shirts who supported Mussollini.

The Irish Fascist were the Blue-shirts lead by Owen Duffy.

And the British had their version of the Blackshirts called the British Union of Fascists lead by Oswald Mosely.

Niether the Irish or British got much support however some members did go off to fight against the communists in the Civil war in Spain.
