Henry John Temple, 3rd Viscount Palmerston

The Right Honourable Henry John Temple, 3rd Viscount Palmerston (October 20, 1784 - October 18, 1865) was a British statesman who served twice as Prime Minister of the United Kingdom in the mid-19th century. He was in government office almost continually from 1807 till his death in 1865, beginning his parliamentary career as a Tory, and concluding it as a Liberal. He is remembered primarily for having directed British foreign policy as either Foreign Secretary or Prime Minister through most of a thirty five year period when the United Kingdom was at the height of its power. His achievements in that field were many, but some of his aggressive measures drew considerable criticism both in this own time and subsequently.
