1. The Birth of Calcutta: A Historic Beginning
The story of Calcutta begins in the late 17th century, when the British East India Company established trading settlements along the eastern banks of the Hooghly River. Before British influence, the area consisted of three small villages: Sutanuti, Gobindapur, and Kalikata. These villages were home to fishermen, weavers, and traders long before the city began to take shape.
How Calcutta Got Its Name
The name “Calcutta” (later anglicized to “Kolkata”) is believed to have come from the village “Kalikata,” which may have roots in:
- the Bengali word “Kali,” referencing Goddess Kali,
- “kalikshetra,” meaning the land of Kali, or
- “khal,” meaning a canal or ditch.
Regardless of its origin, the name signifies the region’s long-standing cultural depth.
Establishment of Fort William
In 1696, the British constructed Fort William, marking the beginning of Calcutta’s transformation into a major colonial hub. This fort later became the center of British military and administrative activities, setting the stage for Calcutta’s rise as a powerful metropolitan center in Asia.
2. Calcutta as the Capital of British India
Between 1772 and 1911, Calcutta served as the capital of British India. During this era, the city experienced monumental changes:
Architectural Growth
The British built remarkable structures that still grace the city’s landscape:
- Victoria Memorial
- Writers’ Building
- St. Paul’s Cathedral
- Howrah Bridge (completed later in 1943)
- Indian Museum
These buildings represent various architectural styles—from Indo-Saracenic to Gothic Revival.
The City of Palaces
Calcutta earned the nickname “City of Palaces” for its grand colonial mansions, wide avenues, and imposing administrative buildings.
Cultural Blossoming
The city also became the epicenter of the Bengal Renaissance, a period marked by advancements in literature, science, education, and art. Legends such as:
- Rabindranath Tagore
- Bankim Chandra Chattopadhyay
- Swami Vivekananda
- Jagadish Chandra Bose
- Satyendranath Bose
rose to worldwide prominence.
This cultural explosion gave Calcutta a legacy that still enriches India’s identity.
3. The Journey Through the Freedom Movement
Calcutta played a crucial role in India’s independence struggle. It served as:
- a hub for revolutionary activities,
- a center of intellectual discussions, and
- a base for several nationalist newspapers.
Movements like the Swadeshi Movement gained momentum here, making the city an influential force in shaping India’s freedom story.
4. Transition to Modern Kolkata
On January 1, 2001, “Calcutta” officially became “Kolkata”, reflecting the Bengali pronunciation and honoring the region’s heritage.
Today, Kolkata is known for:
