Question

Why did Napolean decide to abandon his plans to re-establish the French Empire in America?

Answer 1

At the time, Napoleon was establishing a French Empire that would stretch across mainland Western Europe and turn into the biggest power in the world.

This also put it against the other great powers including its most fierce rival, Great Britain.

With one of the largest armies in history and multiple wars going on, Napoleon sold of American colonies and used the funds to establish an Empire closed to home, that would be easier to manage.
