Armed revolution by Subhas Bose - Phase Europe

The factors contributing to  the "plan of armed revolution" of Subhas Chandra were ;
i) Heritage of a royal family :  Netaji's family history went back for some 27 generations starting from Dasarath Bose of Dakshin - Rarhi (south Bengal) at Mahinagar, 14 miles south of Calcutta. At least two of the ancestors  - Mahipati, Financve and War mimnister to the then King of Bengal and Gopinath, Finance Minister and Naval commander to a latter king of Bengal were among Netaji's ancestors.
ii) Influence of Swami Vivekananda : Vivekananda entered the  life of Subhas Chandra when he was barely fifteen ,i.e., in 1911. It was Vivekananda who gave him a principl that he could cling to . When he was not in a position to decide his way the works of the Swamiji  - the saffron- dressed Hindu monk of India became his life time. Protest or revolt against injustice was learnt by Subhas from Vivekananda. In 1913 when he was only 15 and passed Matriculation securing 2nd position in the University, a legendary figure Aurobindo influenced him by his patriotic action, sacrifice for motherland, and deeper philosophy.
iii) Mentors of Subhas Chandra - 1. Swami Vivekananda, 2. Aurobindia, 3. Benimadhab Das

 Beni Madhab Das (Bengali: বেণী মাধব দাস) (1866 – 1952) was an erudite Bengali scholar, a renowned teacher and a great patriot in British India. Subhas Chandra Bose was his student at Ravenshaw Collegiate School and he left an inedible mark in the mind of his young student, as acknowledged in his book Bharat Pathik. When Bose was under internment and had decided to leave India, he wanted the blessings of his teacher, and so a clandestine meeting was organized for the purpose. A number of his other students occupied important positions in life. His personal life of dedication and devotion inspired all his students on to an eventful life. He was what was referred to as an exemplary teacher.
iii) Changed his policy and programme for gaining Independence of India ; While he was in Europe (1933-36), he answered to a question by Mussolini, "are you for reformist or revolutionary methods for achieving Indian Independence ?",  that he preferred revolutionary to reformist methods. Mussolini said then you have a chance.
iv) Inspired by : 1. Lenin, 2. De Valera, 3. Kamal Ataturk
