In 1987, the federal government decided the creation of an Assembly of Representatives (Spanish: Asamblea de Representantes) of the Federal District. This assembly, elected by the inhabitants of the Federal District, had limited legislative powers. Nonetheless, it was the first time since 1928 that the inhabitants of the Federal District recovered some oversight over their local affairs. Eventually, in 1993, full home rule was granted to the Federal District by the federal government, with the creation of an elected Head of Government of the Federal District and a great expansion of the legislative powers of the Assembly of Representatives of the Federal District, which was also renamed the Legislative Assembly.

The first session of the Legislative Assembly of the Federal District ran from 1997 to 2000. Since its installation the Legislative Assembly has been renewed three times.
