5 paragraph essay about: What has influenced the development of our government??

Students will apply this question to their study of how the U.S. government has evolved, including:
Paragraph 1: introduction
paragraph 2: the philosophers and their influence on the founding fathers and documents
Paragraph 3 : debates to create the constitution
paragraph 4 : the principles and ideas contained in our founding documents
Paragraph 5: Conclusion

Answers

Answer:The single most important influence that shaped the founding of the United States comes from John Locke, a 17th century Englishman who redefined the nature of government. ... The duty of that government is to protect the natural rights of the people, which Locke believed to include life, liberty, and property.

Explanation:Democracy was not created in a heartbeat. In a world where people were ruled by monarchs from above, the idea of self-government is entirely alien. Democracy takes practice and wisdom from experience.

The American colonies began developing a democratic tradition during their earliest stages of development. Over 150 years later, the colonists believed their experience was great enough to refuse to recognize the British king. The first decade was rocky. The American Revolution and the domestic instability that followed prompted a call for a new type of government with a constitution to guarantee liberty. The constitution drafted in the early days of the independent American republic has endured longer than any in human history.

Where did this democratic tradition truly begin? The ideas and practices that led to the development of the American democratic republic owe a debt to the ancient civilizations of Greece and Rome, the Protestant Reformation, and Gutenberg's printing press. But the Enlightenment of 17th-century Europe had the most immediate impact on the framers of the United States Constitution.

The Philosophes

Europeans of the 17th century no longer lived in the "darkness" of the Middle Ages. Ocean voyages had put them in touch with many world civilizations, and trade had created a prosperous middle class. The Protestant Reformation encouraged free thinkers to question the practices of the Catholic Church, and the printing press spread the new ideas relatively quickly and easily. The time was ripe for the philosophes, scholars who promoted democracy and justice through discussions of individual liberty and equality.
