[1][2] Lang was first elected to the New South Wales Legislative Assembly in 1913 and served continuously until 1946.

Lang's initial ministry was confronted with extended cabinet strife, centred on Albert Willis.

[3] Defeated by a Nationalist/Country coalition led by Thomas Bavin and Ernest Buttenshaw at the 1927 election, Lang again won government at the 1930 election, in the middle of the Great Depression.

This ministry covers the period from 4 November 1930 until 13 May 1932[4] when the Governor of New South Wales, Sir Philip Game used the reserve power of The Crown to remove Lang as Premier (see Lang Dismissal Crisis), and appointed Bertram Stevens as Premier.

The composition of the ministry was announced by Premier Lang on 4 November 1930 and covers the period up to 13 May 1932.
