I'm Portuguese. I Speak Portuguese. I Speak Galician. And it is in fact the same language. Altought numorous castilian words and castilian influence is present in galician.

Another error:
Portugal declared independence from Kingdom of Leon in 23 of June 1128.

Portugal was independent when the Count of Portugal turned to be the king of Portugal - the year was 1139 (Till today there are many countries that are independent and have a prince, for example, as the head of State.)

The king of Leon and Castille recognized Portugal as an independent country in 1143.

The pope recognized Portugal as a full independent and cristian nation in 1179.

So, declaration of Independence: 1128 Recognition: 1143
1139 and 1179 ?!?!?!?!?!?! What?????????????? Never even eard of that dates, not even at history classes! Only when reading some history books.
