Answer:
The major differences between the Declaration of Independence and I Have a Dream speech are:
Purpose:
The Declaration of Independence explained the justifications and necessities for America's political separation from Britain and declared the colonies independent states. The I Have a Dream speech called for an end to racial inequality and the realization of true equality and justice for African Americans in the United States.
Audience:
The Declaration of Independence was addressed to King George III of Britain and the British Parliament, formally announcing the colonies' break from the British Empire. The I Have a Dream speech was directed at the larger American public, especially African Americans, appealing to the nation's conscience and sense of justice.
Means of Change:
The Declaration advocated and legitimized violent revolution and political separation as the means to bring about change. The I Have a Dream speech called for nonviolent protest and civil disobedience to challenge the status quo and achieve social and economic justice.
Authorship:
The Declaration of Independence was primarily written by Thomas Jefferson. The I Have a Dream speech was delivered by Martin Luther King Jr. though it incorporated themes and phrases from King's earlier writings and speeches.
In summary, while both texts are iconic examples of demanding justice and equality, their purposes, audiences, means of change and authors significantly differ. The Declaration of Independence focuses on political independence while the I Have a Dream speech emphasizes social and economic justice.
