“I am not afraid to be called a politician,” declared Paul Martin Sr., defending his life’s work in politics. “Next to preaching the word of God, there is nothing nobler than to serve one’s fellow countrymen in government.” First elected to the House of Commons in 1935, Martin served in the cabinet of four prime ministers and ran for the Liberal Party leadership three times. This book examines his remarkable career as a liberal reformer and politician who tackled the issues of his day with consummate political skill and gritty determination. Cutting a broad swath through the history of twentieth-century Canada, Greg Donaghy uses extensive interviews and untapped archival sources to challenge the prevailing view of Martin as simply an ambitious Windsor ward heeler and party operator. Martin embraced a tolerant politics of compromise and accommodation that sought to unite Canadians in search of a more just and equitable world. Though some mocked his ambition and doubted his progressive politics, his resolute championing of health care and pension rights, new meanings for Canadian citizenship, and internationalism in world affairs would leave an indelible mark on Canada’s political landscape.
