Even though Spain at various times ruled Portugal, Portuguese is not really Hispanic ....so I’m told ....
The penninsula was called “Hispania”.
“Spain” never ruled Portugal, as Spain didn’t exist until 1469 with the combining of the Kingdoms Aragon and Castile. Portugal was recognized as an independant Kingdom in 1143 by the Kingdoms of Leon and Castile. The Church recognized it as a legitimate Kingdom in 1179.
