The Portolá and Anza expeditions were instrumental in the settlement of what was later to become a major city in the United States. What motivated the Spanish to move north into Alta, California? Who were the first settlers? What was their journey like? What happened to the native tribes who had been here for many hundreds of years? These questions were answered by presenter Steve Johnson.
