The late-20th century issue that could have been inspired by Mercier's words was the Quebec Referendum.
We are talking about Honoré Mercier, Premier of Quebec, when he delivered his speech on June 24, 1889. He referred to the Quebec referendum when he said: "This province... is Catholic and French and shall remain Catholic and French. All the while asserting our friendship and our respect for the representatives of the other races and religions, all the while claiming our eagerness for giving them their fair share in every aspect ... we solemnly declare that we shall never renounce our rights that are guaranteed by treaties, by law, and by the constitution."
Mercier (1840-1894) was the ninth Premier of the province of Quebec, a renowned politician of the Liberal Party of Quebec.
