The creation of Wario allowed them a character of their own to "symbolize their situation." Nintendo originally considered making him a German character before he developed into an Italian much like Mario.
While it's assumed that, like Wario, Waluigi is most likely Italian, the lithe purple villain's nationality has been shrouded in mystery.
History. Waluigi was born in Sorrento Italy with his brother Wario. Waluigi and his brother has been in Sorrento for 20 years, but thanks to their bad behavior, they have been abandoned from their families.
The designer said "Super Mario Bros. isn't set in Japan, but [Mario is] Japanese. The name Mario sounds Italian, but he isn't Italian. They were really able to capture that ambiguity."

Was German: Wario originally spoke German in Mario Kart 64 -- his voice actor says it's because Nintendo told him Wario was German. But Wario's voice was later re-recorded with an Italian accent, and he's remained Italian ever since.

Nintendo. Some would say that because Wario and Waluigi have Italian accents they are as Italian as their counterparts. But there is a ton of evidence suggesting that they could be a bevy of nationalities including German, British, Japanese, Greek, Alienic, or simply residents of the Mushroom Kingdom.
Luigi is a masculine name of Italian origin, meaning “renowned warrior.” It is derived from the German name Ludwig, combining the Old High German words hlūt and wīg, which means “famous” and “war,” respectively.
The original Mario Bros. depicted Mario and Luigi as Italians in New York, with the television series and films specifying them as originating from the borough Brooklyn. Mario's infancy, in which he was transported by a stork to the Mushroom Kingdom, was first depicted in Super Mario World 2: Yoshi's Island.
Wario's last name is Wario. Wario has never really had a confirmed last name as far as I know. There's some weird thing that people go on about with his last name being “Scapelli” but that's never been in any official material.
In spite of that, comments made by one of Nintendo's most fabled designers cast doubt on if Mario is Italian. While Mario has long been believed to be Italian thanks to his accent, there's evidence that he's actually Japanese. Masayuki Uemura designed Nintendo's first home console, the Famicom.
You may not remember that a few characters had different voices early on though, with Luigi and Wario being voiced by different people in Mario Party 2 and the Japanese version of Mario Kart 64. Now Wario's original voice actor, Thomas Spindler, has come forward with a revelation – Wario was originally German.
Super Show!” introduced Mario (Lou Albano) and Luigi (Danny Wells) as Italian American plumbers from Brooklyn. Then, in the early 1990s, Nintendo of America hired Charles Martinet to voice Mario in the “Super Mario” games, with directors stating in his audition, “You're an Italian plumber from Brooklyn.”
The super brothers' family, however, remains firmly Italian, with actors Rino Romano, John DiMaggio and Jessica DiCicco playing their uncles and mother, respectively. And Martinet, at least, does get the plum voice role of Mario and Luigi's father.
Peaches Christ (stage name for Joshua Grannell) is an American underground drag performer, emcee, filmmaker, and actor.
Bowser is a surname. It is of Norman origin and was given to a person who frequently used the informal Norman greeting beu sire, which means "good sir", or "fine sir".
Yoshi is a Japanese name.
So they got Italian-American plumbing brothers. But in actuality, the Mario brothers are Italian born and raised, and English is their second language.
Wario's Father was a minor character in the SMG4 series. As his name suggests, he was the father of Wario, as well as Waluigi. He mainly appears in flashbacks.
Waluigi is a fictional character in the Mario franchise. He plays the role of Luigi's arch-rival and accompanies Wario in spin-offs from the main Mario series, often for the sake of causing mischief and problems.
He is Luigi's evil doppelganger and Wario's adopted brother. He and his brother are homeless crooked criminals running around the Mushroom Kingdom, trying to gain money by any means, such as: scamming people, robbing banks, joining alongside other villains (namely SMG3), or simply a Taco stand.
