English Chileans (Spanish: Anglochilenos) are citizens of Chile who are descended from English people who have emigrated. They are estimated to number 550,000-820.000 (5%-6% of the national population). Since the Port of Valparaíso opened its coasts to free trade in 1811, the English began to congregate in Valparaíso. The first to arrive brought with them tools, articles of china, wool and cotton, with instructions to return with copper and hemp. This was the first exchange of what would become a deep-rooted commercial relationship between the UK and Chile.
