After General Jose de San Martin landed in Paracas Bay in September 1820, the Mayor José Bernardo de Tagle received a letter from San Martin dated November 20, 1820, inviting them to join the independence movement.
According to the "Libro rojo" of the Trujillo council, containing the records between 1820 and 1823, on January 6, 1821, they signed the declaration and proclaimed the city independent.
Trujillo, which included what is now Tumbes, Piura, Lambayeque, La Libertad, Cajamarca, San Martín and Amazonas - almost all of northern Peru, was henceforth released from Spanish rule.
[2][3]The Independence Day of Trujillo is celebrated every year on December 29, in the city is commemorated as a civic date.
The day is declared a holiday for the whole province and the festivities take place including numerous cultural events and ceremonies.
