Research the subject of America's freedom. Search for books, journals and CDs, or other information sources, such as newspapers and visual media, in your local or school or college library. Use the Internet to search for topics related to freedom in America.
Note key points; these could be events that triggered a revolution for freedom, personalities that fostered the importance of freedom in people's minds. You may derive your idea for the essay from such key points. Remember to write down the details of the source from which you derived the information, to quote as a reference for your essay. This should include the name of the book, newspaper or website, as well as the author and date of publication.
Decide on the topic or thesis for your essay. Freedom is a broad term that has numerous topics under its fold. You may want to talk about the importance of freedom in general, or about freedom of speech in America -- or you may want to take readers on a journey through the evolution of freedom -- post World War I.
Start your essay. Consider opening with important facts and information, quotations or anecdotes. Whatever your opening strategy, introduce your thesis statement at the end of the introduction paragraph, where it will serve as a junction to the main body of the essay.
Build your essay body around the central theme. Engage readers using facts and information. Strive to answer why, where and what -- as well as when, who and how -- to orient your readers. Keep transitions from one paragraph to another smooth, by interconnecting the current with the preceding, wherever possible. Keep your writing simple, clear and concise.
Conclude the essay. You could do this by connecting the last paragraph to the introduction by restating a word or phrase. Consider closing with a reply, in case you have opened the essay with a question.
Proofread your essay. Revisit the essay several times for fresh perspectives and alter your ideas and writing accordingly.
