Which countries did Britain fight against during the Battle of Trafalgar?

The Battle of Trafalgar, a pivotal naval engagement in 1805, wasn't just Britain versus one enemy; it was a clash against a combined force. To understand why Spain and France are the correct answer, we need to remember the Napoleonic Wars. Napoleon Bonaparte, the French Emperor, aimed to invade Britain, and Spain was allied with France at the time. Their combined naval power posed a significant threat. The battle took place off the coast of Spain, near Cape Trafalgar. Admiral Lord Nelson, a British naval hero, led the British fleet to a decisive victory, crippling the French and Spanish navies and securing British naval dominance for over a century. So, while France was certainly a key player, it's crucial to remember that Spain was fighting alongside them. The Netherlands wasn't a major naval power involved in this specific battle, although they had been a rival to Britain at sea in the past.
