Background: Burke was born in Dublin, Ireland. His mother Mary nee Nagle (c. 1702-1770) was a Roman Catholic who hailed from a declasse County Cork family (and a cousin of Nano Nagle), whereas his father, a successful solicitor, Richard (died 1761), was a member of the Church of Ireland; it remains unclear whether this is the same Richard Burke who converted from Catholicism. The Burke dynasty descends from an Anglo-Norman knight surnamed de Burgh (Latinised as de Burgo) who arrived in Ireland in 1185 following Henry II of England's 1171 invasion of Ireland and is among the chief "Gall" families that assimilated into Gaelic society, becoming "more Irish than the Irish themselves". Burke adhered to his father's faith and remained a practising Anglican throughout his life, unlike his sister Juliana who was brought up as and remained a Roman Catholic.
Context: In 1774, Burke's Speech to the Electors at Bristol at the Conclusion of the Poll was noted for its defence of the principles of representative government against the notion that elected officials should merely be delegates:  ... it ought to be the happiness and glory of a representative to live in the strictest union, the closest correspondence, and the most unreserved communication with his constituents. Their wishes ought to have great weight with him; their opinion, high respect; their business, unremitted attention. It is his duty to sacrifice his repose, his pleasures, his satisfactions, to theirs; and above all, ever, and in all cases, to prefer their interest to his own. But his unbiased opinion, his mature judgment, his enlightened conscience, he ought not to sacrifice to you, to any man, or to any set of men living. These he does not derive from your pleasure; no, nor from the law and the constitution. They are a trust from Providence, for the abuse of which he is deeply answerable. Your representative owes you, not his industry only, but his judgment; and he betrays, instead of serving you, if he sacrifices it to your opinion.  Political scientist Hanna Pitkin points out that Burke linked the interest of the district with the proper behaviour of its elected official, explaining, "Burke conceives of broad, relatively fixed interest, few in number and clearly defined, of which any group or locality has just one. These interests are largely economic or associated with particular localities whose livelihood they characterize, in his over-all prosperity they involve."  Burke was a leading sceptic with respect to democracy. While admitting that theoretically, in some cases it might be desirable, he insisted a democratic government in Britain in his day would not only be inept, but also oppressive. He opposed democracy for three basic reasons. First, government required a degree of intelligence and breadth of knowledge of the sort that occurred rarely among the common people. Second, he thought that if they had the vote, common people had dangerous and angry passions that could be aroused easily by demagogues; he feared that the authoritarian impulses that could be empowered by these passions would undermine cherished traditions and established religion, leading to violence and confiscation of property. Third, Burke warned that democracy would create a tyranny over unpopular minorities, who needed the protection of the upper classes.
