The flag of Rio de Janeiro features alternating blue and white quadrants, representing Portugal's influence as well as purity, justice, and vigilance. In the center is an eagle holding a blue shell with the date "April 9, 1892", when the first state constitution was enacted. The flag also features motto "to manage public affairs with righteousness" and symbols of sugar cane and coffee, Rio's main products. Traditional Rio cuisine is influenced by Portuguese dishes like cod, oxtail, and the iconic feijoada, a black bean stew often served with pork. Popular Rio sports include skateboarding, slacklining, kitesurfing, football, and samba dancing.
