The Great Depression spread to Britain primarily due to the interconnectedness of the global economy and the decline in international trade. As the United States, the world's leading economic power at the time, experienced a severe economic downturn, it resulted in a decrease in demand for British exports. This decrease in demand caused unemployment to rise, industrial production to decline, and ultimately led to an economic contraction in Britain. Additionally, the collapse of major banks and financial institutions in the United States triggered a global banking crisis, which further contributed to the spread of the Great Depression to Britain and other countries.
