Biography of John Locke | English thinker.
English thinker (Wrington, Somerset, 1632 - Oaks, Essex, 1704). This multifaceted man studied at the University of Oxford, where earned a doctorate in 1658. Although  his specialty was medicine and maintained relations with renowned  scientists of the time (such as Isaac Newton), John Locke was also a  diplomat, theologian, Economist, Professor of ancient Greek and  rhetoric, and achieved renown for his philosophical writings, which laid  the foundations of liberal political thought. 
John Locke
Locke was approached with such ideas as a physician and Secretary was of the Earl of Shaftesbury, leader of the Whig, adversary of the absolutism of the monarchy in the England of Charles II and Jacobo II. Converted  to the defence of parliamentary power, the own Locke was pursued and  had to take refuge in Holland, where he returned after the triumph of  the "glorious revolution" English of 1688.
Locke was one of the great ideologists of English Protestant elites that, clustered around the whigs, arrived to check the status by virtue of the revolution; and,  as a result, his thinking has exercised a decisive influence on the  political Constitution of the United Kingdom until today. He defended religious tolerance towards all the Protestant sects and even non-Christian religions; but  the interested and partial nature of his liberalism was highlighted by  excluding the right to tolerance both atheists and Catholics (the  confrontation of the latter with the Protestants being the key of the  religious conflicts that were bleeding to the British Isles and Europe  as a whole).
John Locke
In his most significant work, two essays on civil government (1690),  sat the basic principles of liberal constitutionalism, postulating that  every man is born with natural rights which the State aims to protect:  fundamentally, the life, liberty and property. Based  on the thinking of Hobbes, Locke supported the idea that the State is  born from a 'social contract' originally, rejecting the traditional  doctrine of the divine origin of power; but,  unlike Hobbes, he argued that the Pact did not lead to the absolute  monarchy, but it was revoked and he could only lead to a limited  Government. 
The  authority of the State was the will of the citizens, who would be  disconnected from the duty of obedience when their rulers conculcaran  these inalienable natural rights. The people  would thus not only the right to modify the legislative discretion (idea  from where comes the practice of periodic elections in liberal States),  but also the overthrow rulers diminished by a tyrannical exercise of  power (idea that Jefferson and the American revolutionaries supported  for rebelling against Great Britain in 1776 as well as the French revolutionaries to rise up against the absolutism of Luis XVI in 1789). 
Locke defended the separation of powers as a way of balancing them together and prevent any degenerated towards despotism; but,  to the supremacy of a legislature representative of the majority, can  be considered him also a theorist of democracy, towards which end up  evolving liberal regimes. By legitimate it is,  however, no power should exceed certain limits (hence the idea of  putting them in writing in a Constitution). 
This  type of ideas inspired liberalism Anglo-Saxon (reflected promptly in  the constitutions of Britain and United States) and, indirectly, also to  the rest of the world (through French, such as Montesquieu and Voltaire  illustrated). Less incidence had properly  philosophical thought from Locke, based on a theory of knowledge  empiricist inspired by Bacon and Descartes.
