Inspite of dividing his time betweeen law and poetry, he engaged himself in Politics during WWI and supported Indian involvement in the war. He also supported Khilafat movement which Jinnah did not. He had close contact with Muslim political leaders like Maulana muhammad Ali and Muhammad Ali Jinnah but was critical about the mainstream Indian National Congress , which he regarded as dominated by Hindus and was disappointed with the League when in 1920s it was devided into two factions one prop-British led by Muhammad Sufi and the other centrist led by Jinnah.In Nov 26, he contested for a seat in the Punjab Legislative Assembly from the Muslim District Lahore but was defeated . He supported Jinnah's constitutional proposal for safegurding the interest of the Muslims. Iqbal's second book in English , the reconstruction of Religious thought in Islam , was published in 1930. He was elected President of the Muslim League in its session in Allahabad in 1930. In his Presidential address on 29 Dec, 1930, Iqbal outlined a vision of an independent state for Muslim-majority provinces in the north-western India.
But this was a unique departure from the aims and objectives of All Idia Muslim League when it was formed in 1906.He reiterated that;
" I would like to see the Punjab, North-West Frontier Province , Sindh and Balochistan amalgamated into a single state. Self-government within the British Empire or without the British Empire, the formation of a consolidated North-West Indian Muslim stateappears to me to be the final destiny of the muslims, at least of North-West India."
In his speech, Iqbal emphasised that unlike Christianity, Islam came with "legal concepts" with "civic significance", with its "religious ideals", considered as inseparable from social order. Iqbal, thus, stressed not only the need for a separate state for the political unity of Muslim Communities, but the undesirability off blending the Muslim population into a wider society not based on Islamic principles . He thus became the first politician to articulate what would become as the Two -nation Theory. h4e would travel across Europe and West Asia to garner political and financial support for the League, and he stressd his proposal for Independence.
But the feudal classes in Punjab as well as Muslim politicians did not approve his ideas.
