2026 marks the Semiquincentennial or 250 year anniversary of the signing of the Declaration of Independence. You may have seen an increase in discussions about the American Revolutionary War and its impact (on a national and global level). You may be planning to attend one of the many events which are being held to commemorate America250, such as the RAI America 250 events.
Over this week, we will be releasing brief blogposts aimed at helping researchers find primary sources on the American Revolutionary War, in a variety of different formats, geographic focus and subject areas. It is intended to help those interested in the War, who may already have some general knowledge on the subject, to dig deeper into the different primary sources available and start their own research journey.
