What would the world look like if Iran never existed?

Well, people would still be wearing skirts and togas since Iranians invented pants and pajamas. The Parthians and Persians were the first to wear pants.

Iranians made a LOT of contributions to Mathemathics and Science. A lot of inventions wouldn't be here if it weren't for them.

Rome would have conquered the world. It's true because Iran was the only nation that defeated Rome numerous times. If there was no Iran, Rome would have eventually gotten to China!

Here are a list of Iranian contributions that I copied and pasted from one of my previous aswers:

Virtually all European scholars claim Arabic music has Persian origins

These are just some of the contributions

ADDED DETAILS:

-Amin jan, they didn't but they did introduce it to the west.

-Kratos, you make an excellent point. Almost all allied equipment was working on Iranian oil. The Germans didn't have oil rich countries supplying cheap oil to them like Iranians did for America, USSR, and Britania.

And we did stop the Ottomans from conquering all of Asia. Infact, we were one of the reasons that they expanded more to the west than to the east. :)

if iran never existed the world would be so different. Iran was the first country to give freedom of religion, freedom from slavery, and able women to work just like men with the same freedoms all provided by cyrus the Great. The US declaration of independence was based off cyrus declaration. Also the United Nations is BASED off Cyrus' declaration. it shaped a lot in the world. too bad people nowa days dont know this.

i believe just some country make world better and help others to live better , and another countries are leecher or something like that.

u know if some people make civilization ,some people use this civilization ,and some people destroy this civilization ,iran and persians are who make civilization.

its make different Iran from Kenya or Kenya from Arabs.

The world would suck if there was no Iran.

Persia was a great kingdom that spread accross most of Asia at one stage...if Iran never existed Persia would surely still be there.

world would regret for ever for not having persia

well,The ottoman Empire would be the real king of the world.& also the result of The World War II would be different for sure...

Same as it does now. God, or Allah or whatever name you care to use in His wisdom created the Earth without political boundaries. Man, in his ignorance, drew national boundaries.

the world would have fewer carpets

then i won't hear CNN/BBC.....talking bout .number of deaths and children...wid no school or family......its horrible:(
