The term 'prime minister' - or 'first minister' refers to the office of head of government (but not head of state). Although there have been leaders of nations right through history, it is believed that the term 'prime minister' - the head of an elected government rather than the king or queen - was given first to Robert Walpole, First Earl of Orford, (26th Aug 1676 - 18th March 1745) who was elected Prime Minister of Great Britainin 1721, allthough his position as 'prime minister' was not official, but gradually became esablished during his period of office under King George I and George II. His official title was 'First Lord of the Treasury', a title held by prime ministers of the now United Kingdom (Great Britain and Northern Ireland) ever since. In fact, even today, on the prime minister's residence in London (No. 10 Downing Street) the plaque on the front door still states 'First Lord of the Treasury' and not 'Prime Minister'.
