How did Stephen Harper help create the Conservative Party of Canada in 2003?

In 2003, Stephen Harper played a pivotal role in consolidating Canada's right-wing political forces by engineering the merger of the Canadian Alliance and the Progressive Conservative Party.12

Following his election as leader of the Canadian Alliance in 2002, Harper sought to overcome the electoral limitations that had historically split the conservative vote and prevented either party from effectively challenging the governing Liberal Party of Canada. By 2003, recognizing that neither the Alliance nor the Progressive Conservatives could defeat the Liberals on their own, Harper successfully led the negotiations to unite the two groups.132

This effort culminated in December 2003, when more than 90 percent of the members from both parties endorsed the merger. The Conservative Party of Canada was officially registered on December 8, 2003, creating a unified opposition that would eventually lead to Harper becoming prime minister in 2006.412
