Why was India the Jewell in the crown of the British empire?

India was considered the "jewel in the crown" of the British Empire due to its vast resources, including spices, textiles, and later, raw materials like cotton and tea, which were highly valued in global markets. The subcontinent's strategic location also facilitated trade routes to Europe and beyond. Additionally, India's large population provided a significant market for British goods, fostering economic interests that were crucial for sustaining the empire. This combination of wealth, resources, and market potential made India essential to British imperial ambitions.
