Calcutta vs Delhi during the British Period

 If by British era you mean roughly 18th century to 1947, Calcutta and Delhi played very different roles. The most interesting comparison is that Calcutta became the British imperial capital first, while Delhi remained the symbolic centre of Indian sovereignty.

The biggest difference

Calcutta was Britain's working capital

The East India Company developed Calcutta into the centre of its operations after the British acquired increasing control over Bengal.

After the Battle of Plassey (1757) and the acquisition of the Diwani of Bengal, Bihar and Orissa in 1765, Bengal became the financial foundation of British expansion.

Calcutta consequently became:

Company headquarters → capital of British India → port → financial centre → intellectual centre.

This is why Calcutta became so disproportionately important in the 18th and 19th centuries.

Delhi was India's symbolic capital

Delhi possessed something Calcutta could never acquire:

centuries of political legitimacy.

Delhi had been associated with the Delhi Sultanate and, most importantly, the Mughal Empire.

When the British crushed the uprising of 1857, they formally ended the Mughal dynasty and exiled Bahadur Shah Zafar.

But paradoxically, the British subsequently recognised that Delhi's symbolic power was too important to ignore.

So in 1911, George V announced the transfer of the capital from Calcutta to Delhi.

That was not primarily an economic decision.

It was an imperial political statement:

Britain was presenting itself as the successor to India's great imperial traditions.

5 fascinating contrasts

1. Calcutta looked outward; Delhi looked inward

Calcutta was connected to the Bay of Bengal, Indian Ocean and global trade.

Delhi was connected to the land-based political history of northern India.

2. Calcutta represented commerce; Delhi represented sovereignty

A merchant, banker or exporter naturally gravitated toward Calcutta.

A ruler seeking legitimacy gravitated toward Delhi.

3. Calcutta was more cosmopolitan commercially

Calcutta became a meeting point for British, Armenians, Jews, Chinese, Parsis, Marwaris, Bengalis and many other communities, alongside a huge colonial bureaucracy.

Delhi's cosmopolitanism was older and deeply connected to Persianate, Mughal and North Indian culture.

4. Calcutta produced ideas; Delhi produced political symbolism

The Bengal Renaissance generated enormous intellectual change—Rammohan Roy, Vidyasagar, Bankim Chandra, Tagore and others.

Delhi's importance lay more in its historical memory, Urdu culture, courtly traditions and eventually its role as the political capital.

5. Their fortunes reversed

This is perhaps the most interesting part.

1757: Calcutta begins its extraordinary rise.

1772: Calcutta becomes British India's capital.

1857: Mughal Delhi is destroyed politically.

1911: Capital moves from Calcutta to Delhi.

1947: Delhi becomes the capital of independent India.

So, over roughly two centuries:

Calcutta rose because of the British Empire; Delhi regained prominence because of India's political history.

One-line version for your website

Calcutta was the British Empire's economic and administrative engine in India; Delhi was the historical symbol of Indian imperial power that the British eventually made their imperial capital.

And there is a wonderful three-city historical sequence for your website:

Murshidabad → Calcutta → Delhi

Murshidabad: Nawabi Bengal's financial-political capital
↓
Calcutta: British India's commercial and administrative capital
↓
Delhi: British India's imperial capital and independent India's national capital

That gives you a remarkably coherent 300-year story of how the centre of power shifted within eastern and northern India.
