Historical romance is a genre consisting of books that take place in a historical setting with the developing romance of the main character being the focus. Some eras such as the Regency have many more titles available than others, but the genre is always expanding. Some publishing houses define historical romance as romances that take place before the Vietnam War, whereas others define it as before WWII.
Historical romances examine the ways that romantic relationships might've developed in times where values and social mores were different from present time. They also examine how love can thrive even against backdrops of war and injustice, and how they run into the same joys and sorrows as those in present day - loyalty, betrayal, heartache, flirtation, jealousy, humour, etc. all find their way into historical romance.
