In April, 1847, at Athens, the house of Don Pacifico, a Portuguese Jew born on British soil at Gibraltar, was destroyed by a mob of Jew-baiters. As a British citizen he put in a claim for damages and asked the foreign office to collect it. Palmerston had other scores to settle with Greece, and when his demands met with slow response, he sent a British fleet to the Piraeus to lay hands on Greek shipping. Greece appealed to France and Russia for protection. The trouble grew to such proportions that the British Parliament took it up. The Lords censured the government for its harsh and unjust treatment of a friendly state. In the Commons a vote of confidence in the foreign policy was moved, and on this question Lord Palmerston delivered the greatest speech of his life. It was an exposition and defense of his entire official career, and no argument could break the force with Englishmen of the triumphant sentence in which it culminated. "I fearlessly challenge the verdict which this House, as representing a political, a commercial, a constitutional country, is to give on the question before it; whether the principles on which the foreign policy of this country has been conducted, and the sense of duty which has led us to think ourselves bound to afford protection to our fellow- subjects abroad, are proper and fitting guides for those who are charged with the government of England, and whether as the Roman in the days of old held himself free from indignity when he could say 'Civis Romanus sum,' so also a British subject, in whatever land he be, shall feel confident that the watchful eye and the strong arm of England shall protect him against injustice and wrong!" This "Civis Romanus" speech raised the orator to the highest pitch of popular regard. But the premier had found him a very troublesome colleague on account of his confirmed practice of committing the government on important matters without consulting with his chief. He was warned by the Queen's personal memorandum that this habit must cease, but an unpardonable case occurred in 1851. Prince Louis Napoleon Bonaparte, president of the French republic, executed his coup d'etat and overthrew the constitutional government. Without consulting Queen or Premier, and contrary to their express desire, Palmerston, in conversation with the French ambassador, approved the bold stroke of the Prince-President. For this indiscretion Lord Russell summarily dismissed him.
