First, do in - depth research on the historical period. Read historical books, documents, and diaries. For example, if writing about the Renaissance, study the works of famous artists and thinkers of that time. Second, create believable characters that fit the historical context. They should have the values, attitudes, and behaviors of the people from that era. Third, use vivid descriptions to bring the historical setting to life. Describe the smells, sounds, and sights.
One needs to have a passion for history to write an explicit historical novel. Research is key. Look into not only the major events but also the small details like daily routines, food, and clothing. For example, if writing about the Middle Ages, learn about the types of food people ate. Develop characters who are products of their time. They could be peasants, knights, or nobles. Incorporate historical facts seamlessly into the story. Don't just list them but weave them into the plot and character development. Also, be true to the historical context in terms of social and cultural norms.
To write an explicit historical novel, start with choosing a specific historical period that interests you. Then, immerse yourself in it. Visit museums, historical sites if possible. For instance, if your novel is set in ancient Egypt, go to an Egyptian museum to see the artifacts. Build your plot around real historical events or trends. Make your characters interact with these events in a natural way. Also, be careful with the language. Use words and phrases that were common in that period but also make sure it's understandable to modern readers.
