September 7 is an important date in Indian and world history, associated with major political developments, banking history, freedom movement milestones and the birth anniversaries of several well-known Indians. The day is also observed globally for causes related to clean air, international police cooperation and literacy.

One of the significant events in Indian history took place on September 7, 1931, when the Second Round Table Conference opened in London. Mahatma Gandhi participated as the sole official representative of the Indian National Congress. The conference discussed India's constitutional future, minority representation and other political issues. However, the discussions failed to produce a consensus on several key questions.
Another important milestone occurred on September 7, 1906, when the Bank of India was founded in Mumbai by a group of prominent businessmen. It began with a single office and later developed into one of India's major banking institutions. The bank was nationalised in July 1969 along with 13 other major banks.
September 7 also has significance in India's modern economic history because the establishment of Bank of India formed part of the expansion of Indian-owned commercial banking during the early 20th century. The period around 1906 saw growing interest in Indian-owned financial institutions, particularly during the Swadeshi movement.
Several prominent Indians were born on September 7.
