VIENNA — Forced out of Hungary, Central European University marked its relocation to Vienna on Friday with a bittersweet ceremony that amounted to a victory for Hungary’s far-right prime minister, Viktor Orban, in his campaign against liberal values.

Founded and endowed after the fall of the Iron Curtain by George Soros, the billionaire financier and philanthropist, the university promoted democracy and liberal thought in a region where they had been suppressed for a century under fascism and communism.

But it ran afoul of Mr. Orban’s increasingly authoritarian and nativist government, which has turned Mr. Soros — a Jew who was born and raised in Hungary, but has lived most of his life in the West — into a kind of all-purpose boogeyman.

Mr. Soros announced on Friday that his Open Society Foundations had committed 750 million euros, about $825 million, to an effort by Central European University and Bard College in New York to build a global network for colleges and universities to work together and support each other.
