The real (, meaning "royal", plural: "réis" or [archaic] "reais") was the unit of currency of Portugal from around 1430 until 1911. It replaced the "dinheiro" at the rate of 1 real = 840 dinheiros and was itself replaced by the "escudo" (as a result of the Republican revolution of 1910) at a rate of 1 escudo = 1000 réis. The "escudo" was further replaced by the euro at a rate of 1 euro = 200.482 "escudos" in 2002.
