Why is Spain called ‘Spain’? -

It might seem fake, but this is actually what historians has come to agree after many years of study:

Carthaginians soldiers landed for the first time on what is known as Spain in the 5th Century BC.
When they arrived and discovered it, Spain was so full of rabbits (literally crowded) that those animals were running wild everywhere. There were so many even the coast where the boats landed was crowded with them.

Upon this scenario, the Carthaginian soldiers shouted at once: “ Span! Span!” which meant “Rabbits! Rabbits!”.

From then on, that land was known as “The Land of Rabbits”.

After that, Phoenicians also named Spain “I-sch Phannim” which means “Rabbit Island”

Even more, Spain was well-known by the Roman Empire for its rabbits and its olive oil. By that time, Spain was known as “Hispania”, which is a Latin literal translation of “I-sch Phannim”. Furthermore, at that time, Hispania’s coins, coined by Emperor Adriano (1st and 2nd century AD) reflected that curiosity.
You can have a look at the coin from that age here:

You can see Emperor Adriano on one side and a man holding an olive branch with a rabbit at his feet.

With the course of time, the language spoken in Hispania derived from Latin after the Roman Empire Fall to Castellano (Spanish), and Hispania became España, with its characteristic eñe letter (Ñ), losing its H, which is a mute (silent/non-pronounced) consonant in Spanish.

If you find this etymology interesting, you should know that almost every country is named after one of four things:
