After two nationalist European strongmen won overwhelming victories in elections on Sunday, April 3, 2022, one of the first foreign leaders to congratulate both was not from a neighboring country or a regional ally. It was Russian President Vladimir Putin. The parliamentary elections in Hungary and Serbia both brought landslide wins for the two countries' longtime, pro-Putin leaders — Hungarian Prime Minister Viktor Orban and Serbian President Aleksandar Vucic.
