Why wasn't Portugal conquered by Spain?

Thanks to Reddit/Portugal where I was informed then watched this very informative 10 minute-long YouTube clip
For those of us wishing to become more familiar with Portugal and its history; well worth watching


Being used to hearing all these names in Portuguese, it was quite amusing/distracting to hear the narrator’s pronunciation :smile: Seems to be in line with what we’re taught at school, although I’d maybe disagree with the comment that Portugal wasn’t interesting enough to Spain - they tried to invade a number of times throughout history and jumped at the chance to annex it in 1580, as mentioned in the video.
