The front represents the portrait of Juan Manuel de Rosas, born March 30, 1793, was an Argentine military leader and politician, governor of the province of Buenos Aires from 1829 to 1832 and from 1835 to 1852. Leader of the Federalist Party, he defended a centralist and authoritarian approach, using state terror and propaganda to maintain control, notably through its secret police, the Mazorca. Although he favored the interests of landowners and maintained a measure of stability, his repressive regime attracted criticism. His power ended in 1852 after his defeat at the Battle of Caseros by Justo José de Urquiza, and he lived in exile in the United Kingdom until his death on March 14, 1877.
