The battle for Vietnam waged between the communist-ruled North of the country, and the US-backed south, lasted almost 20 years, from 1955. It spilled over into neighbouring countries, and resulted in the deaths of an estimated 3.8 million people - half of them civilians. It was a brutal, un-winnable conflict, which reshaped global geopolitics.

But how did what might have been a little local trouble in Southeast Asia evolve into an international conflict? Why did the rise of an anti-colonial, national movement prompt such a ferocious playing out of the Cold War? And what were its consequences?

This is a Short History Of The Vietnam War.
