The first Día de los Indianos parade happened in the 1920s, and people wore white formal clothes from the time period of their ancestors' migration. The event has been popular ever since.
Día de los Indianos is connected to the environment because the environment influenced why people moved from the Canaries to the Americas. A lot of people struggled economically in the Canaries from the seventeenth to nineteenth centuries because of droughts and poor conditions for growing crops. In the Americas, conditions were ideal for crops like sugar cane. That is one of the reasons why people were able to benefit economically from moving to the Americas.
