Minho River
The former Kingdom of Galicia, then including modern Portugal as far south as Coimbra, was given by Alfonso VI as a county to his son-in-law Raymond of Burgundy. However, concern for Raymond's growing power led Alfonso in 1096 to separate Portugal and Coimbra from Galicia and grant them to another son-in-law, Henry of Burgundy, wed to Alfonso VI's illegitimate daughter Theresa. Henry chose Guimarães as the base for this newly formed county, the "Condado Portucalense", known at the time as "Terra Portucalense" or "Província Portucalense," which would last until Portugal achieved its independence, recognized by the Kingdom of León in 1143. Its territory included much of the current Portuguese territory between the Minho River and the Tagus River.
