How has Portugal been able to survive on the Iberian Peninsula?

by Joseon194

Same as the title above, how on earth did Portugal actually survive on the Iberian Peninsula when there was big neighbor Spain right to the east of her? It almost seems astounding to me that Spain never just swallowed up Portugal considering it was not a great power, in any sense, compared to France and England.
