For over 40 years, from 1951 till retirement in 1990, Vahabzadeh worked at Azerbaijan State University as a professor of “Contemporary Azerbaijani Literature”, albeit with two years gap. In 1980 he became both a member of the Azerbaijani Academy of Sciences and deputy of the Milli Majlis (parliament) of the Azerbaijan SSR. His rise in the political ranks of Soviet Azerbaijan was aided by penning titles such as his 1976 Leninlə Sohbet, but politically he had long been a noted nationalist, suffering a two-year expulsion from his university for publishing the 1959 poem Gulustan in which he drew attention to the division of the Azerbaijani people as a result of the 1813 Treaty of Gulistan. Vahabzadeh is cited as one of the figures of the Azerbaijani intelligentsia whose pronouncements in 1988 contributed to the rising tensions between the Azerbaijani and Armenian populations of Shamakhi District that led eventually to the Kərkənc village swap. Having been deputy of the Supreme Soviet of the Republic of Azerbaijan since 1980, Vahabzadeh continued his parliamentary duties following independence gaining election to Azerbaijan's national parliament in 1995 and again in 2000. On 15 April 1995 Vahabzadeh was awarded with the prestigious Istiglal Order for his contributions to the national independence movement of Azerbaijan by the then President of Azerbaijan Heydar Aliyev.
