History
Lawn tennis in India can be traced back within the first decade of the establishment of the Wimbledon championships with early local championships being established in places like Punjab (1885) and Calcutta (1887). However, there was no national championships, in 1910 colonial officers of the British Raj established the All India Lawn Tennis Championships in Allahabad which was 10 years before the All India Tennis Association was founded. The championships staged both men's and women's singles play and also doubles. In 1946, the All-India Championships tournament was renamed the National Lawn Tennis Championships of India by the India Lawn Tennis Association.

The tournament was hosted at different cities around India and was also played on different surfaces, such as grass courts (1910–59, 1964–66, 1969, 1970, 1973), hard courts (1967) and clay courts (1960–61, 1974–79). This tournament was also held in conjunction with the Northern India Championships for the years 1961 to 1967.
