by asserting certain natural and legal rights, including a right of revolution. Its original purpose was to announce independence, and references to the text of the Declaration were few in the following years. Abraham Lincoln made it the centerpiece of his policies and his rhetoric, as in the Gettysburg Address of 1863. Since then, it has become a well-known statement on human rights, particularly its second sentence: "We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness." The declaration was made to guarantee equal rights for every person, and if it had been intended for only a certain section of people, Congress would have left it as "rights of Englishmen". Stephen Lucas called it "one of the best-known sentences in the English language", with historian Joseph Ellis writing that the document contains "the most potent and consequential words in American history". The passage came to represent a moral standard to which the United States should strive. This view was notably promoted by Lincoln, who considered the Declaration to be the foundation of his political philosophy and argued that it is a statement of principles through which the United States Constitution should be interpreted. The Declaration of Independence inspired many similar documents in other countries, the first being the 1789 Declaration of United Belgian States issued during the Brabant Revolution in the Austrian Netherlands. It also served as the primary model for numerous declarations of independence in Europe and Latin America, as well as Africa (Liberia) and Oceania (New Zealand) during the first half of the 19th century. Background By the time the Declaration of Independence was adopted in July 1776, the Thirteen Colonies and Great Britain had been at war for more than a year. Relations had been deteriorating between the colonies and the mother country since 1763. Parliament enacted a series of measures to increase revenue from the colonies, such as the Stamp Act of 1765 and the Townshend Acts of 1767. Parliament believed that these acts were a legitimate means of having the colonies pay their fair share of the costs to keep them in the British Empire. Many colonists, however, had developed a different perspective of the empire. The colonies were not directly represented in Parliament, and colonists argued that Parliament had
