What are the original Latino-americans come from?

Below is the spread of the Latino culture

1) Ancient Greeks colonised and settled in parts of Italy, over time their culture changed slightly and would eventually lead to the creation of the Roman Empire

2) Many years later Romans became the first official Latin culture

3) Many years later Romans colonised and settled in parts of Spain

4) Many years later Spain colonised most of south America

And that is how south America has become known as Latin America.

However you may find misleading information on the internet stating that Spanish are the original Latinos but this is not true.
