[Q]: I know that the answer to the question "What happened in 1868?" is in "Palmerston died in 1865, and after a brief ministry led by Russell, Derby returned to power. In 1866, Victoria attended the State Opening of Parliament for the first time since Albert's death. The following year she supported the passing of the Reform Act 1867 which doubled the electorate by extending the franchise to many urban working men, though she was not in favour of votes for women. Derby resigned in 1868, to be replaced by Benjamin Disraeli, who charmed Victoria. "Everyone likes flattery," he said, "and when you come to royalty you should lay it on with a trowel." With the phrase "we authors, Ma'am", he complimented her. Disraeli's ministry only lasted a matter of months, and at the end of the year his Liberal rival, William Ewart Gladstone, was appointed prime minister. Victoria found Gladstone's demeanour far less appealing; he spoke to her, she is thought to have complained, as though she were "a public meeting rather than a woman".". Can you tell me what it is?
