In May 1934 Nehru and Sukarno were both in detention. Nehru was in Dehra Dun jail sentenced to two years after having been found guilty of making a seditious speech. Sukarno, also arrested for sedition, was in exile on the island of Flores. For both men it was a period of reflection and analysis, a time to review the progress of the nationalist movement and make some assessment of their own contributions to it. Nehru, more given to introspection than Sukarno, composed his autobiography during this time, and continued with the historical studies he had commenced during earlier prison terms. Sukarno in exile spent much of his time getting to grips with Islam, primarily, it would appear, to prepare arguments to convince the leaders of the Islamic movements in Indonesia of the compatibility of Islam with modernization and progressive political action. In this respect, like Jinnah, he was attracted to the figure of Kemal Attaturk whose general outlook on the relationship between state and religion he endorsed.
