Which long-running political alliance in the 1860s helped advance Confederation and constitutional reform?

• A. The Liberal-Progressive Alliance
• B. The Great Coalition of 1864
• C. The Confederation Pact of 1867
• D. The Union of Canada West and East

Answer: (B)

The essential idea here is that cross-party cooperation can unlock large-scale constitutional change. In 1864, leaders from different factions in the Province of Canada formed the Great Coalition, bringing together Reformers and Conservatives to break the political deadlock and push a unified plan for a federal union and constitutional reform. This alliance, involving figures like John A. Macdonald, George-Étienne Cartier, and George Brown, created a united front that enabled the conferences and negotiations leading to Confederation and the framework for Canada’s federal system. Its lasting impact was turning regional rivalries into a workable blueprint for a self-governing federation, culminating in the constitutional arrangement that would become the British North America Act of 1867. Other options don’t reflect this pivotal, cross-party effort from the 1860s that directly advanced Confederation.
