World War One
Archer Evermonde 1912 - 1923
In post during the Muggle First World War, Evermonde passed emergency legislation forbidding witches and wizards to get involved, lest they risk mass infractions of the International Statute of Secrecy. Thousands defied him, aiding Muggles where they could.

Occasionally, a Potter made it all the way to London, and a member of the family has twice sat on the Wizengamot: Ralston Potter, who was a member from 1612-1652, and who was a great supporter of the Statute of Secrecy (as opposed to declaring war on the Muggles, as more militant members wished to do) and Henry Potter (Harry to his intimates), who was a direct descendant of Hardwin and Iolanthe, and served on the Wizengamot from 1913 - 1921. Henry caused a minor stir when he publicly condemned then Minister for Magic, Archer Evermonde, who had forbidden the magical community to help Muggles waging the First World War. His outspokenness on the behalf of the Muggle community was also a strong contributing factor in the family’s exclusion from the ‘Sacred Twenty-Eight’.
Pottermore - The Potter Family
The wizards of America had played their part in the Great War of 1914-1918, even if the overwhelming majority of their No-Maj compatriots were ignorant of their contribution. As there were magical factions on both sides, their efforts were not decisive, but they won many victories in preventing additional loss of life, and in defeating their magical enemies.

Owen Jones: Are you implying that Dumbledore had a hand in ending the Second World War [JKR laughs] by his defeat of the Dark wizard Grindelwald -
JKR: In 1945.
OJ: - in 1945?
JKR: I may well be implying that.
OJ: Do you enjoy having stuff in the wizard world connecting with Muggle - Muggles - history?
JKR: Well, I really do, yes, because I think that's what adds to the believability of the books. I think that's one of the reasons readers can imagine themselves so readily into the wizarding world because they can see how it does interconnect with our world. So it's both secret and apparent, but we, Muggles, don't have the perception to see what's right under our noses, of course.

JKR: I'm going to tell you as much as I told someone earlier who asked me. You know Owen who won the competition to interview me? He asked about Grindelwald. He said, “Is it coincidence that he died in 1945,” and I said no. It amuses me to make allusions to things that were happening in the Muggle world, so my feeling would be that while there's a global Muggle war going on, there's also a global wizarding war going on.
ES: Does he have any connection to --
JKR: I have no comment to make on that subject.
MA: Do they feed each other, the Muggle and wizarding wars?
JKR: Yeah, I think so. Yeah. Mm.
