“How can I get my proposal accepted for presentation at the annual Pikes Peak Regional History Symposium?” Refer to the Proposal Guidelines. Following the guidelines is especially important as your proposal will be evaluated by the panel of readers using those guidelines.
The annual theme offers wide latitude in your selection of topic but the most important thing to remember as you organize your essay/presentation is that the readers are not looking for a retelling of an already well-known event or historical person. Beyond a brief summary or biography of the event or person, if needed, the readers will be looking for a unique interpretation of the evidence in your telling of the story as well how it makes a new contribution to the historical narrative or opens up new avenues of research.
