, the nationwide Rodeo competition. Rodeo is the second most popular sport in Chile after football. It began in roughly the 16th century during the rule of Governor García Hurtado de Mendoza. At the time, the cattle in Chile were not well identified and it was not uncommon for the animals to get lost. To help prevent the loss, Governor Hurtado proclaimed that, in Santiago, every 24th and 25 July, the commemoration of Saint Jacob - patron saint of the city -, the cattle would be gathered in the Plaza de Armas de Santiago to be branded and selected. This is basically how Chilean rodeo began.
