Why did the British want to control the coastal cities?

The British sought to control coastal cities primarily for strategic and economic reasons. Coastal cities served as vital ports for trade, enabling the British to facilitate the import and export of goods, particularly valuable commodities like spices, textiles, and later, opium. Additionally, controlling these cities allowed the British to establish military bases, ensuring naval dominance and protection of their shipping routes against rivals. This control also facilitated the expansion of the British Empire, allowing for greater influence over local economies and politics.
