Eduardo, of Spanish and Portuguese origin, translates to 'guardian' or 'protector'. It is derived from the Germanic elements 'eudo', meaning 'wealth' or 'prosperity', and '-hardu', which signifies 'strong' or 'brave'. The name gained popularity through its association with several notable figures, including Eduardo I of Portugal and Eduardo VII of the United Kingdom. A historical variant of the name is Edward, which has been used by many monarchs throughout European history.
The name Eduardo experienced a significant rise in popularity from the late 1960s to the early 1990s, peaking at 21 births in both 1993 and 1994. However, it has since declined, with as few as 5 births recorded in recent years (2006, 2008). Overall, there were a total of 433 babies named Eduardo between 1960 and 2010.
