Welser was a German banking and merchant family, originally a patrician family from Augsburg, that rose to great prominence in international high finance in the 16th century as financiers of Charles V, Holy Roman Emperor. Along with the Fugger family, the Welser family controlled large sectors of the European economy, and accumulated enormous wealth through trade and the German colonization of the Americas. The family received colonial rights of the Province of Venezuela from the Charles I King of Spain in 1528, becoming owners and rulers of the South American colony of Klein-Venedig (within modern Venezuela), but were deprived of their rule in 1556. Philippine Welser (1527–1580), famed for both her learning and her beauty, was married to Archduke Ferdinand, Emperor Ferdinand I's son.
