Matthew Fielding Locke
After the war, Locke returned to Mississippi, and in 1849 married Elizabeth A. Biue. Shortly thereafter they moved to Upshur County, Texas. He established a plantation about 13 miles (21 km) northeast of present-day Gilmer and founded the nearby town of LaFayette (which he named after his son, LaFayette C. Locke, who was born in 1850). Locke began the first of two terms as a state representative in 1855 in the Sixth Texas Legislature. In the Seventh Legislature, Locke was elected Speaker of the House "pro tempore" on 26 December 1857 when Speaker William S. Taylor took ill. When Taylor resigned on 18 January 1858, Locke was elected Speaker over Reps. Isaac N. Dennis and John Henry Brown, 39 votes to 14 and 13, respectively.
Age of Enlightenment
Locke is known for his statement that individuals have a right to "Life, Liberty and Property" and his belief that the natural right to property is derived from labor. Tutored by Locke, Anthony Ashley-Cooper, 3rd Earl of Shaftesbury wrote in 1706: "There is a mighty Light which spreads its self over the world especially in those two free Nations of England and Holland; on whom the Affairs of Europe now turn". Locke's theory of natural rights has influenced many political documents, including the United States Declaration of Independence and the French National Constituent Assembly's Declaration of the Rights of Man and of the Citizen.
