The present is a time frame that is usually happening at the moment. For example, 1850 is the past, 2017 is the present, and 2037 is the future.
The purpose of the government is to "establish Justice, insure domestic Tranquility, provide for the common defence, and promote the general welfare."
So, mostly everything to do with society's welfare.

Historical fiction is when the book is based on historic occurrences though the characters and/or their actions are made-up. “The Contest” is about the Romans and the Roman emperor, Nero. Nero was, in fact, a real person, and the majority is based on actual facts, making it a work of historical fiction.
