How did the Fenian Raids contribute to confederation?

The Fenian Raids, conducted by Irish nationalists seeking to liberate Ireland from British rule, highlighted the vulnerabilities of British North America to external threats. These incursions raised fears of potential invasions and underscored the need for a more unified and robust defense among the provinces. As a result, discussions around confederation gained momentum, leading to the realization that a united Canada could better protect its territory and interests. Ultimately, the raids accelerated the push for confederation, contributing to the formation of the Dominion of Canada in 1867.
