This is a high-quality gilt brass 2 piece uniform button produced in Paris and supplied for use by the Imperial Mexican government during the Second Mexican Empire (1864–1867). The button is of two-piece construction and bears the backmark “Perfectionné Paris”, a known Parisian button maker active in the mid-19th century and frequently involved in export commissions.

The obverse displays a crowned eagle with wings displayed, surmounted by a European-style imperial crown and resting above a laurel or oak wreath. This iconography reflects the imperial heraldic style adopted under Emperor Maximilian I, which differed markedly from earlier republican Mexican emblems and drew heavily on contemporary European court traditions.

Buttons of this quality were not intended for line infantry use. The absence of regimental numerals or branch devices, combined with the refined gilding and construction, indicates use by imperial court, household, or palace staff, or possibly ceremonial or administrative officials attached to the Emperor’s household.

French manufacture was standard for imperial Mexican court uniforms and accoutrements during this short-lived period, as many items were ordered directly from Paris due to limited domestic production capabilities. Surviving examples are scarce, reflecting both the brief duration of the Second Empire and the subsequent political upheaval following its collapse in 1867.
