The surname Rigaudias is of French origin and it is derived from the given name Rigaud, a variant of the name Roger, which was brought to France by the Normans. The Normans were a group of Northmen who settled in Norway and later invaded England in 1066, led by William the Conqueror, who went on to become the King of England. The name Roger is thought to be derived from the Old Norse name Hrörek, meaning "famous ruler." Over time, the surname Rigaudias may have been formed through various spelling variations, including Rigaudy, Rigaudeau, and Rigaudeix, among others.
The surname Rigaudias is believed to have originated from France, specifically in the region of Normandy. It is an occupational name derived from the Old French word "rigalde," which means a steward or administrator. This occupation was an essential role in managing the affairs of a noble family or a feudal lord's estate. Over time, as families moved and settled in different regions, variations in the spelling of this surname emerged. The name Rigaudias is one such variation, suggesting that it may have originated from a specific branch or lineage of the original bearers of the surname Rigalde.
The surname Rigaudias has its origins primarily in Portugal and Brazil. In Portugal, it is most prevalent in the regions of Minho, Braga, Porto, and Lisbon, reflecting historical migration patterns from rural areas to urban centers. In Brazil, the name is most common in the southeastern states of São Paulo, Rio de Janeiro, and Minas Gerais, likely due to immigration from Portugal during colonial times or later, such as the coffee boom era in the 19th century. It is also found in smaller numbers in other Portuguese-speaking countries like Angola, Mozambique, and Cape Verde, as well as in some Spanish-speaking countries, reflecting broader historical migration patterns.
The surname Rigaudias has several variations and spellings due to differences in transliteration, transcription, and regional pronunciations over time. Some possible versions include Rigaudyas, Rigaudius, Rigaudiis, Rigaudio, Rigaudi, Rigaudys, Rigaudis, and Rigaudioz. These variations may arise due to factors such as geographical location, immigration records, or errors in document translation. It is important to note that these variations can make it challenging to trace the genealogy of individuals with this surname, especially when researching historical records. However, understanding these variations can help in locating and connecting family members across generations and regions.
One of the notable individuals with the surname Rigaudias is José de Ribas y Rigaudias, a prominent figure during the Spanish colonial period in South America. He served as a military officer and political leader, playing a significant role in defending Spain's territories against British invasions. His most notable achievement was the successful defense of Montevideo, Uruguay, against a 20-month siege by the British from 1806 to 1807, an event known as the Siege of Montevideo. In contemporary times, António Rigaudias is recognized as a Portuguese professor and researcher in the field of computer science and artificial intelligence. He has made substantial contributions to the study of swarm intelligence, multi-agent systems, and intelligent control. Additionally, he has published numerous articles and books on these subjects, solidifying his place among leading experts in the field.

A notable figure with this surname is Pedro Rigaudias, a 16th-century chronicler who wrote extensively about the history of the city of Braga and its bishops. The name also spread to other Portuguese-speaking regions due to migration and colonization, including Brazil where it remains relatively common. Variations of the name include Rigaudi, Rigaldo, and Rigaudo. The earliest recorded spelling of the surname appears to be Rigaldo in 1526 in Portugal.
