How did the colonists justify ending their political ties to britain?

The Founding Fathers drew vigorously from English logician John Locke in building up America's First Principles: the acknowledgment of unalienable rights, the Social Compact, and restricted government. Locke wrote a few progressive scholarly pieces, particularly "A few Thoughts Concerning Education," "A Letter Concerning Toleration," and "An Essay Concerning Human Understanding." His most prominent work which was powerful to the Founders were his First and Second Treatise of Civil Government (1689). Locke safeguarded the Glorious Revolution of 1688, in the Second Treatise, where he clarified that in a condition of nature individuals were allowed to seek after and shield there claim intrigues which caused war. To escape war, the general population built up governments to secure peace. To Locke "no flexibility" existed without a Social Compact of laws, since "freedom is to be free from limitation and brutality from others; which can't be the place there is no law." Unlike his English contemporary Thomas Hobbes, Locke contended that where governments secured the unalienable privileges of people; they had no power past that which was important to ensure those rights. The Declaration of Independence (1776) and the Constitution of the United States (1789) mirrors his considerations in which the pilgrims based their entitlement to end political bonds with Great Britain whose oppressive King and Parliament had held on in preventing the rights from claiming the homesteaders who were British subjects.
