Why are lions depicted so much in European stuff?

Maybe lions once ranged further north. I really don't know.

From Wiki

Lions inhabited parts of Europe during the Holocene and even historic times and formed a subspecies called Panthera leo europaea. They lived in ancient Rome, ancient Greece, southern Russia, coastal parts of Saudi Arabia, and western Asia including: Turkey, Armenia, Azerbaijan, Georgia, Iran, Afghanistan, Pakistan and India. It is also suggested by historical evidence, although not certain, that they lived in Portugal, Spain, southern parts of France, Italy, and the Balkans beyond Greece.

It's thought many were in the Northern Hemisphere at one time.
Possible also that the Romans may have brought some with them when they invaded many northern countries as a show of strength.
probably lots of theories but i doubt we'll ever really know.

Maybe because of what lions stand for. Power. Perhaps a name that involves lions gives power, or makes the person who invented a lion-isa name for a product feel like it will sell better, because of a 'powerful' name. ;)

Not to forget the lion on the Peugeot logo

I learnt in history thar British lions aren't actually lions...
They're panthers!

Lions are symbol of beavery and power.so they are widely used to boast your military or country

I'm guessing it's because of Rome.

Read the Bible?

Hmmmmmmm as opposed ta chickens

They're still the King of Beasts wherever you are. The lion depicts bravery in heraldry...

Symbol of strength. Ironically, it's the females that hunt and raise young.

I seem to recall reading that lions did once exist in Europe but went extinct.
