Portuguese is a Romance language spoken by about 210 million people mainly in Brazil (Brasil) and Portugal, and also in Angola, Mozambique (Moçambique), Cape Verde (Cabo Verde), Guinea-Bissau (Guiné-Bissau), São Tomé e Principe, East Timor (Timor-Leste) and Macau. There are also communities of Portuguese speakers in the USA, Canada and a number of other countries.
Portuguese is a descendent of Latin, which was brought to the Iberian Peninsula by Roman soldiers, settlers and merchants from 218 BC. The earliest records of a distinctly Portuguese language appear in administrative documents dating from the 9th century AD. In 1290 King Denis decreed that Portuguese, then simply called the 'Vulgar language' should be known as the Portuguese language and should be officially used.
