While it is generally known that Mahatma Gandhi had great affection for Jawaharlal Nehru and that this was one of the most important factors in the latter succeeding him as the leading figure in the Indian National Congress and becoming the Prime Minister of India, it is seldom realized that the relationship between the two was one of the most determining factors in the history of the Congress and consequently in that of modern India, both before and after the achievement of Independence. To bring all this into focus has been the main objective of this work. Part one of the book consists of the texts of letters exchanged between Gandhi and Nehru and part two shows the impact of the Gandhi-Nehru relationship on the history of the Indian National Congress. Some of the moving writings of Nehru on Gandhi after the latter's passing away, showing Nehru's deep attachment to the master, follow. The introduction not only sums up the materials in two parts, but also discusses the impact of the Gandhi-Nehru relationship on the history of India during the Nehru Era. The book will be of tremendous interest to the general public as well as to scholars of modern Indian history in general and of Gandhi and Nehru in particular.
