Ignatieff married Princess Natalia Nikolayevna Meshcherskaya (1877-1944) in Nice, France, on April 16, 1903. They would have seven children, all boys, two of whom died as infants.
He was a graduate of the University of Kiev. Afterward, he entered the Imperial Ministry of Agriculture, eventually becoming a director of one of its departments in 1909. He was appointed in 1912 as Assistant Minister of Agriculture. In 1915, during the First World War, he was appointed Minister of Education. He held that position until December 1916.
During the October Revolution, Ignatieff was arrested and was to be executed. However, he was spared by the Polish commissar overseeing his execution, who said that Ignatieff was a good man because he had implemented progressive policies such as Polish language rights while Education Minister. Ignatieff and his family then fled to England in 1919 and lived on a farm in Sussex, before moving to Canada.[1]
In 1925, the family immigrated to Canada and settled permanently three years later in Upper Melbourne in Quebec, where he died on August 12, 1945.
One of Ignatieff's sons, George, was a prominent Canadian diplomat. One of his grandsons, Michael Ignatieff, is an author, Harvard professor, former Canadian Member of Parliament and former leader of the Liberal Party of Canada.
