The term Creole and its cognates in other languages — such as crioulo, criollo, créole, kriolu, criol, kreyol, kriulo, kriol, krio, etc. — have been applied to people in different countries and epochs, with rather different meanings. Those terms are almost always used in the general area of present or former colonies in other continents, and originally referred to locally-born people with foreign ancestry.
In the United States, the word "Creole" usually refers to people of any race or mixture thereof who are descended from settlers in colonial French Louisiana before it became part of the United States in 1803 with the Louisiana Purchase. Some writers from other parts of the country have mistakenly assumed the term to refer only to people of mixed racial descent, but this is not the traditional Louisiana usage. It is now accepted that Creoles form a broad cultural group of people of all races who share a French or Spanish background. Louisianans who identify themselves as "Creole" are most commonly from historically Francophone communities with some ancestors who came to Louisiana either directly from France or via the French colonies in the Caribbean. (Those descended from the Acadians of French Canada usually identify as Cajuns, rather than Creoles.) The term is also often used to mean simply "pertaining to New Orleans". The general perception of a Creole is usually of an olive toned individual. Louisiana's Creole People (Creoles of Color) are of mixed (mainly) French, Spanish, African-American, and Native American heritage
The English word creole derives from the French créole, which in turn came from Portuguese crioulo. This word, a derivative of the verb criar ("to raise"), was coined in the 15th century, in the trading and military outposts established by Portugal in West Africa and Cape Verde. It was originally applied to descendants of the Portuguese settlers who were born and "raised" locally. The word then spread to other languages, probably by the Portuguese slave traders who supplied most of the slaves to South America through the 16th century.
While the Portuguese may have originally reserved the term crioulo to people of strictly European descent, the crioulo population eventually came to be dominated by people of mixed Portuguese and African ancestry. This mixing happened relatively quickly in most Portuguese colonies of the time, due to the scarcity of Portuguese-born women in the settlements, and to a Portuguese Crown policy of encouraging mixed marriages in the colonies.
These crioulos of mixed Portuguese and African descent eventually gave rise to several major ethnic groups in Africa, especially in Cape Verde, Guinea-Bissau, São Tomé e Príncipe, Ziguinchor (Casamance), Angola, Mozambique. However, only a few of these groups have retained the name crioulo or variations of it:
African slaves were imported into the country from the 17th century until the first half of the 19th century. Due to their multiple ethnic roots and to the extension of the country, the Brazilian slaves and their descendants did not constitute a cohesive ethnic group. On the other hand, as in the Portuguese colonies in Africa, people of mixed Portuguese and African ancestry soon came to constitute a large segment of the population, in which there were no sharp class divisions based on degrees of "Africanness".
As a consequence, the term crioulo never became the name of an ethnic group. Instead it is simply a racial label, now highly offensive.
In Spanish-speaking Latin America, the word criollo (cognate and closest equivalent of English Creole) generally refers to people of unmixed European (typically Spanish) descent born in the New World. According to the Spanish American caste system, people with European and indigenous origin who possessed 1/8th or less of Amerindian ancestry, were also considered criollos (unlike people with mainly European and some black African ancestry, who were deemed to be mulatto or mixed-raced). In any case, the expression Spanish American criollo is only applicable to people born in the New World.
Throughout the colonial period, a caste system was effectively in force, where the local-born criollos ranked strictly lower than governing peninsulares ("born in the Iberian Peninsula"), despite both being of European ancestry. By the 19th century, this discrimination and the example of the American Revolution and the Enlightenment eventually led the criollo elite to rebel against the Spanish rule. Enlisting in many cases the support of the even lower classes — castizos, mestizos, cholos, mulattos, amerindians, zambos, and ultimately blacks — they engaged Spain in the Mexican War of Independence (1810–1821) and the South American Wars of Independence (1810–1826), which ended with the break-up of former Spanish Empire in America into a number of independent republics.
The meaning of Filipino changed drastically during the Philippine Revolution for Independence against Spain in 1896. It was adopted by nationalist movements and transformed into a national designation that encompassed the entire population of the Philippines, especially the descendants of the native Austronesian peoples. In fact, the meaning of Filipino today is the opposite of its colonial meaning, since it tends to refer only to the predominantly native Austronesian population and excludes the mestizos of mixed Spanish descent, as well as the non-mixed criollos, who are seen as foreigners despite the fact that they are Filipino like everybody else. This has to do with the American colonization of the Philippines after the Spanish-American war, as racial labels were applied to non-white peoples, and the term "Filipino" was mistakenly used by Americans in U.S. newspapers and magazines as a racial label (instead of as a nationality) to refer to those in the islands of pre-dominantly Austronesian descent - a definition that is the complete opposite of its original definition, and continues to this day.
In parts of the Southern Caribbean the term "Creolean" is used to refer to a French-speaking person of Caucasian ethnicity. Especially if they are from the smaller islands belonging to Saint Vincent.
In the Seychelles, the term includes all ethnic groups, regardless of background.
In Réunion, creole is a more inclusive term that denotes all those born on the island. However, those of African/Malagasy and French origin are the ones usually classified as being ethnically Creole.
