Which country was the first to use tanks in combat?

France made a prototype to test but all together the british was the first to use tanks on the battlefield

I believe British forces deployed the first tanks during World War 1 at the Battle of Flers-Courcelette on 15 September 1916

Britain altered native american societies culturally because some of the indian tribes were friends with the british and thought them their culture and the british did the same.some of the tribes didn't like the british and fought against them with france, some tribes didn't want anything to do with the europeans and left them alone.trade with the british changed them economically because they were now trading food for things like guns and blankets.
