There is no easy answer to where paprika comes from. While paprika is closely associated with Hungary and Hungarian cuisine, paprika peppers did not arrive in that part of the world until the mid to late 16th century. The origin of all peppers can be traced to South America, where they grew wild and were distributed throughout South and Central America, mostly by birds. Eventually, peppers were cultivated, and native traders travelling through these regions carried them across the Caribbean as cargo in dugout canoes.
If you wonder whether you can substitute one for the other, the answer is yes. You would use a lot less red chili powder, even if it is of the milder variety, than you would paprika. In fact, the best way to go about this is add it slowly and in small amounts, till you get the heat factor that you want. In a pinch, you can use paprika instead of red chili powder as well, though you may not get the color that you want and the flavor may be different.
