Travel Trivia Tuesday 30

This month our Destination of the Month is Portugal. Olá, to our fellow Portuguese! Portugal is a country where plenty of Britain's go on holiday and also where some live and enjoy the sunshine. It's also ideal as it's in the same Time Zone (GMT) as the UK. Being a very popular, beautiful country it has come a long way in it's history. What we want to know this week is, What was the name and when was the first county of Portugal founded? And I will give an extra point if you can tell me who founded it!
