Michael Grant Ignatieff is a Canadian public intellectual, historian, politician, the interim leader of the Liberal Party of Canada and the Leader of Official Opposition in Canada. He has held academic positions at Cambridge, Oxford, Harvard and the University of Toronto. An award-winning author, he has also worked as a journalist and documentary film-maker.

Ignatieff lived in the United Kingdom from 1978 to 2000. During this time he was on the staff at both the University of Cambridge and the University of Oxford, and worked as a film-maker and political commentator for the BBC. He lived in the United States from 2000 to 2005; there, he was director of Harvard's Carr Center for Human Rights Policy. He returned to Canada in 2005 and took a position as a visiting professor and seInternational Studies at the Univnior fellow of the Munk Centre for ersity of Toronto. In November, 2005 he was mentioned as a possible Liberal candidate for the next federal election.

In 2006 he was elected as the Member of Parliament for Etobicoke—Lakeshore. Ignatieff was named associate critic for Human Resources and Skills Development in the Official Opposition Shadow Cabinet on February 22, 2006. He left this position on April 7, 2006 to become a candidate for the leadership of the Liberal Party. Front-runner for most of the campaign, he was defeated by Stéphane Dion on the leadership convention's fourth and final ballot. Ignatieff served as the party's deputy leader from December 18, 2006 to November 14, 2008. He was re-elected as Member of Parliament for Etobicoke-Lakeshore in the 2008 federal election.

Ignatieff has been described by the British Arts Council as "an extraordinarily versatile writer," in both the style and the subjects he writes about. His fictional works, Asya, Scar Tissue, and Charlie Johnson in the Flames cover, respectively, the life and travels of a Russian girl, the disintegration of one's mother due to neurological disease, and the haunting memories of a journalist in Kosovo. In all three works, however, one sees elements of the author's own life coming through. For instance, Ignatieff travelled to the Balkans and Kurdistan while working as a journalist, witnessing first hand the consequences of modern ethnic warfare. Similarly, his historical memoir, The Russian Album, traces his family's life in Russia and their troubles and subsequent emigration as a result of the Bolshevik Revolution.

A historian by training, he wrote A Just Measure of Pain, a history of prisons during the Industrial Revolution. His biography of Isaiah Berlin reveals the strong impression the celebrated philosopher made on Ignatieff. Philosophical writings by Ignatieff include The Needs of Strangers and The Rights Revolution. The latter work explores social welfare and community, and shows Berlin's influence on Ignatieff. These tie closely to Ignatieff's political writings on national self-determination and the imperatives of democratic self-government. Ignatieff has also written extensively on international affairs.

Blood and Belonging, a 1993 work, explores the duality of nationalism, from Yugoslavia to Northern Ireland. It is the first of a trilogy of books that explore modern conflicts. The Warrior's Honour, published in 1998, deals with ethnically motivated conflicts, including the conflicts in Afghanistan and Rwanda. The final book, Virtual War, describes the problems of modern peacekeeping, with special reference to the NATO presence in Kosovo.
