The British Empire was a global power that, at its zenith in the early 20th century, governed a quarter of the world's land and people, spreading its influence across continents. Originating in the late 16th century with overseas trade and minor colonies, it expanded significantly through the 18th and 19th centuries, driven by economic interests and military might. This era involved extensive Colonialism, shaping laws and cultures, yet also leading to exploitation and conflict. Its legacy endures, particularly through the modern Commonwealth of Nations.
