From two battalions raised by the Continental Congress in 1775 to the Corps of today: the wars and battles the Marines fought, the leaders who shaped them, and the traditions they carry. **How to read it.** Wars and campaigns are durations, with a picture behind the timeline while they last; battles, milestones and people are moments with their picture. Chapter headings mark the eras. Hover over a cluster of moments to fan it out, and open any moment for its full notes and sources. Related events (a leader and their battle, a battle and its war) are linked. **Sources and images.** Each event links the Wikipedia article it draws on. Images are linked, not copied, from Wikimedia Commons, where most are US government works in the public domain; open an image's original for its author and license. Dates are given in UTC; where only the month or year is known, the notes say so.
