Ordinary Filipinos throughout the country wore either yellow shirts or held masses for Aquino as their way of paying tribute to the woman who once led them in a revolution that changed the course of their country's history. Yellow Ribbons, which were once used during Aquino's battle with Marcos, were tied along major national roads and streets as a sign of solidarity and support for the now deceased Aquino and her grieving family. In popular social networking sites such as Facebook and Twitter, Filipinos posted yellow ribbons in their accounts as a tribute to the former Philippine leader. Following her death, Filipino Catholics called on the Church to have Aquino canonized and declared as a saint. During her lifetime, Aquino was known and praised for her strong spirituality and sincere devotion to the Catholic faith. Days after her funeral, the Bangko Sentral ng Pilipinas (BSP) announced that it supported calls to put the former president on the 500-Peso banknote alongside her husband, Ninoy Aquino.
