The current state flag of Peru was officially adopted on February 25, 1825.
The colors are said to symbolize the Incas and their lasting impact on the country. Also, red and white are the colors chosen by Jose de San Martin, The Liberator. The coat of arms (not shown on the national flag) features a llama and Cinchona tree, important symbols of Peru, and a centered cornucopia representing prosperity.
Peru Coat of Arms:
The Peruvian coat of arms is largely dominated by the central shield, which is divided into three sections. The upper left section show the national animal of Peru, the vincuna.
The upper right section shows the cinchona tree. Cinchona trees are used to make quinine, which is a powerful anti-malaria drug. The lower section shows a cornucopia full of coins. These coins represent the mineral wealth of the country. The Holm Oak Civil crown above the shield signifies victory and glory.
