The real (Portuguese pronunciation: [ʁiˈal], meaning "royal", plural: réis or [archaic] reais) was the unit of currency of Portugal and the Portuguese Empire from around 1430 until 1911. It replaced the dinheiro at the rate of 1 real = 3+1⁄2 libras = 70 soldos = 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.
