I want to know the answer to the following question:
In which year was Vimara Peres knighted?
All the background I'm provided with is that "After annexing the County of Portugal into one of the several counties that made up the Kingdom of Asturias, King Alfonso III of Asturias knighted Vimara Peres, in 868 AD, as the First Count of Portus Cale (Portugal).". Is that enough to answer the question?
Answer: yes
