Some say the recipe for mashed potatoes originates in 1771 when a French man named Antoine Parmentier came up with the idea of having a competition on ways to make potatoes. Having had the idea, it's no surprise that he then won first place and then eventually began cultivating potatoes himself. The story goes that he hired a group of royal soldiers to guard his farm near Paris. But the guards were not vigilant enough; peasants stole Parmentier's crops, effectively introducing potatoes into the cuisine of France and, much later, widespread Europe.

I think we need some clarification here. Are you asking where mashed potatoes were invented? Or do you want to know where modern instant mashed potatoes are made? I don't know if we can definitively answer the first question, because mashed potatoes are so basic. Potatoes are native to the Americas. I don't know if the native peoples mashed their potatoes or cooked them in some other fashion, but I do know that potatoes weren't introduced to Europe until Europeans conquered the Americas. The people in South America had already domesticated the potato by then. It seems reasonable to suppose that they might have boiled their potatoes, and sometimes mashed them, but I don't know if there is any evidence to prove that they did.
