When Lord Palmerston again took a portfolio, it was to be Home Secretary in the coalition cabinet of Lord Aberdeen (1852-55). He had become the warm friend and admirer of Lord Shaftesbury, whose mother-in-law, Lady Cowper, was now Lady Palmerston, the most gracious and skilful helpmeet that any statesman could wish to have. His inclination and his position enabled him to put through much legislation suggested by the philanthropic peer for the welfare of the working- classes. His knowledge of foreign affairs was at the service of the government, and came into active play when the Czar's claim to a protectorate over all Greek Christians in the Turkish empire brought the Eastern Question again to a fever heat, in 1853. The Czar Nicholas had said in a conversation with the British Minister concerning the political weakness of Turkey, "We have on our hands a sick man- -a very sick man; it will be a great mistake if one of these days he should slip away from us before the necessary arrangements have been made." His idea of "arrangements" was that Turkey in Europe should fall under Russian protection, leaving England free to control her direct route to India by way of Cyprus and Egypt. English diplomacy encouraged the Sultan to reject the Russian claim to the uttermost. The result was war. Turkey first declared it against the Russians, who had already invaded her Danubian principalities. Palmerston held that it was the duty of Europe to preserve the balance of power by preventing Russia from aggrandizing herself at the expense of Turkey, and when the Czar refused to withdraw from the principalities England joined with France in declaring the war, which, from the scene of its chief operations against Russia, has since been called the Crimean. Forty years had passed since Waterloo and war was an exciting novelty for British youth. England plunged into it with enthusiasm, but the feeble and incompetent prosecution of the campaign against Sebastopol, with the mismanagement of commissary and hospitals, evoked a storm of opposition, before which the Aberdeen ministry collapsed. Lord Palmerston was the natural choice of Queen and nation to succeed him. He became Prime Minister in February, 1855, and though past his seventieth year, his energy put a new face on the military situation, and his diplomacy gained a substantial advantage over Russia in the Treaty of Paris (March, 1856), which closed the inglorious conflict, and postponed for twenty years her advance toward the Bosphorus. The Queen, who had many reasons to dislike the personality of her chief minister, honored him with the Garter, in recognition of his services to the state.
