The European Parliament backed a motion on Wednesday calling the massacre a century ago of up to 1.5 million Armenians a genocide, days after Pope Francis used the same term.
Although the resolution repeated language previously adopted by the parliament in 1987, it could raise tensions with Turkey, whose president, Recep Tayyip Erdogan, said even before the vote took place that he would ignore the result.
After the vote, the Turkish Foreign Ministry accused the parliament of attempting to rewrite history.
