Hitler was released on parole on 20 December 1924 and Hess ten days later.[33] The ban on the NSDAP and SA was lifted in February 1925, and the party grew to 100,000 members in 1928 and 150,000 in 1929.[36] They received only 2.6 per cent of the vote in the 1928 election, but support increased steadily up until the seizure of power in 1933.[37]
