The Assembly of Notables was a governmental body recognized by the Conservative Party that functioned as a Legislative Power convened by the Supreme Governing Junta. It was composed of 215 members chosen from Mexican citizens of diverse classes and ranks, serving as departmental representatives. Their task was to decide the definitive form of government and, once that decision was made, to offer the Mexican throne to the Austrian archduke Maximilian of Habsburg under a moderate hereditary monarchy.
The Assembly of Notables appointed a Mexican Delegation tasked with offering the Mexican throne to His Majesty Maximilian of Habsburg as representatives of the nation.
