Question

Why was the battle of Trafalgur important?

Answer 1

The consequences of the battle were far reaching. Napoleon’s plan to invade Britain was thwarted. He broke up the camp at Boulogne and marched to Austria where he won the great victory of Austerlitz against the Austrians and Russians.

Trafalgar ensured that Britain’s dominance at sea remained unchallenged for the rest of the 10 years of war against France and continued worldwide for a further 120 years.

Answer 2

It was a pivotal moment in European history. The British navy destroyed 2/3 of the French/Spanish combined fleet while loosing no ships themselves. It established Britain as a significant sea power and made most of Europe a lot more reluctant to engage it.

Had the British lost the battle Britain would have been significantly reduced, if not destroyed as a nation. This would have meant no British Empire, which in turn would have reshaped world history as we know it. Possibly to the point that WWI and WII could not have happened.
