Following the Emancipation Act, how many workers from India and China were employed to replace the liberated slaves?

The Emancipation Act of 1833 abolished slavery in the British Empire, including colonies in the Caribbean. This created a massive labor shortage, particularly on sugar plantations. Plantation owners needed a new source of cheap labor, and they turned to indentured servitude, primarily from India and China. Indentured servitude was a system where people were contracted to work for a fixed period, often several years, in exchange for passage, accommodation, and a small wage. While technically not slavery, the conditions were often harsh and exploitative. Over the decades following the Act, around 2 million indentured laborers were brought to the Caribbean from India and China to fill this gap. This massive influx significantly altered the demographics and cultural landscape of these islands, leaving a lasting legacy that is still visible today. While other numbers might sound plausible, the scale of the labor demand necessitated a workforce of this magnitude to sustain the plantation economies.
