Trade was the key in developing Britain's global empire and dominance. It opened Britain up to lucrative new markets, though which it could sell its domestically produced value-added goods (especially after the beginning of the Industrial Revolution) while importing luxury and exotic goods to drive its wealthy population. Additionally, the importance of trade and the resulting need to secure trade routes drove Britain to develop the world's most powerful navy, which in term secured its global power during its era of dominance.
