A mood of inflated patriotism. The term originated in 1878, when Russian successes in a war against the Ottoman empire had created at the Treaty of San Stefano a Bulgaria that Britain regarded as a threat to its Eastern interests; a popular music-hall song of the time began with the lines: “We don’t want to fight, but by Jingo if we do; We’ve got the ships, we’ve got the men, we’ve got the money too!” Strong anti-Russian feeling developed in Britain, where Disraeli called up reserves for army service and war-fever gripped the country.
