Nationalistic urges? Speak for yourself, you're the nationalist here. If I was a Portuguese nationalist, I would do everything to hide the fact that a Spaniard has held the title of King of Portugal before Afonso Henriques declared independence in 1143.
He did not receive the title of Count of Portugal from Ferdinand I. I am 100% sure of that. In 1065, when he became King of Galicia and Portugal, there was already a Count of Portugal: Nuno Mendes, of the house of Vímara Peres, who held that title from 1050 to 1071. In 1071, he rebelled against Garcia and only then did the latter manage to get the title of "Count of Portugal".
